Surah Al Imran 137-139 So lose not heart, nor fall into despair: for ye must gain mastery if ye are true in Faith.

Al-E-Imran

Many similar ways (and mishaps of life) were faced by nations (believers and disbelievers) that have passed away before you (as you have faced in the battle of Uhud), so travel through the earth, and see what was the end of those who disbelieved (in the Oneness of Allâh, and disobeyed Him and His Messengers). (137) This (the Qur'ân) is a plain statement for mankind, a guidance and instruction to those who are Al-Muttaqûn (the pious - see V.2:2). (138) So do not become weak (against your enemy), nor be sad, and you will be superior (in victory) if you are indeed (true) believers. (139)

Al-E-Imran

Many were the Ways of Life that have passed away before you: travel through the earth, and see what was the end of those who rejected Truth. (137) Here is a plain statement to men, a guidance and instruction to those who fear Allah! (138) So lose not heart, nor fall into despair: for ye must gain mastery if ye are true in Faith. (139)

Al-E-Imran

Sesungguhnya telah berlaku sebelum kamu (contoh kejadian-kejadian berdasarkan) peraturan-peraturan Allah yang tetap; oleh itu mengembaralah kamu di muka bumi, kemudian perhatikanlah bagaimana akibat orang-orang yang mendustakan (Rasul-rasul). (137) (Al-Quran) ini ialah penerangan kepada seluruh umat manusia dan petunjuk serta pengajaran bagi orang-orang yang (hendak) bertakwa. (138) Dan janganlah kamu merasa lemah (dalam perjuangan mempertahan dan menegakkan Islam) dan janganlah kamu berdukacita (terhadap apa yang akan menimpa kamu), padahal kamulah orang-orang yang tertinggi (mengatasi musuh dengan mencapai kemenangan) jika kamu orang-orang yang (sungguh-sungguh) beriman. (139)

Al Quran Surah Al-Anaam 48

Al-Anaam

And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve. (48)

Al-Anaam

We send the Messengers only to give good news and to warn: so those who believe and mend (their lives),― upon them shall be no fear, nor shall they grieve. (48)

Al-Anaam

Dan tiadalah Kami utuskan Rasul-rasul itu melainkan sebagai pembawa berita gembira dan pembawa amaran; kemudian sesiapa yang beramal soleh, maka tidak ada kebimbangan (dari berlakunya kejadian yang tidak baik) terhadap mereka dan mereka tidak akan berdukacita. (48)

The Methodology of the Prophets In Calling To Allaah
by Shaikh Saalih ibn Fawzaan
Translated by Aboo Talhah Daawood ibn Ronald Burbank

All praise is for Allaah, Lord of the Worlds, who ordered us to follow His Messenger (sallallaahu 'alaihi wa sallam) and to call to His Way, and may Allaah send praises and blessings of peace upon our Prophet Muhammad, and upon his family, his companions, and those who truly follow them until the Day of Judgement. To proceed:

Calling to Allaah (ad-Da'wah ilallaah) is the way of the Messenger (sallallaahu 'alaihi wa sallam) and his followers, as Allaah, the Most High, says:

Say, O Muhammad (sallallaahu 'alaihi wa sallam): This is my way, I call to Allaah (i.e to the testification that none has the right to be worshipped except Allaah, alone, with no partner) upon certain knowledge - I, and those who follow me. I declare Allaah free and far removed from all that they associate as partners with Him, and I am free of those who worship anything else along with Him. [Soorah Yoosuf 12:108]

Indeed calling to Allaah was the mission of all the Messengers and their followers, in order to bring the people out of darkness and into light, from unbelief (kufr) to true Faith (eemaan), from shirk to tawheed, and from the Fire to Paradise. This call to Allaah rests upon firm pillars, and is established upon foundations which are absolutely essential. If any of these are missing the da'wah will not be correct and will not produce the desired results - no matter how much effort is expended and time wasted - and this is the reality which we witness with regard to many of the present day calls which are not supported by those pillars and built upon those foundations. These pillars which support the correct da'wah are clearly shown in the Book and the Sunnah, and can be summarised as follows:

1. Knowledge of that which one calls to:

STRIVING IN WORSHIP

STRIVING IN WORSHIP

Al-Hasan al-Basri said, "Whoever competes with you in the Deen then try to surpass him, and whoever competes with you in the matters of this life then throw it back at him." Whenever he missed a Salah in congregation, ibn `Umar radhiallahu `anhu used to fast one day, pray for one whole night and free a slave.

Abu Musa al-Ash`ari used to apply himself so much in worship at the end of his life that he was told, "Why don't you slow down and be gentle with yourself?" He replied, "When the horses are released for a race and are close to the finish line, they give all the strength they have. What is left of my life is less than that." He maintained the same level of devotion and worship until he died.

Mawriq al-`Ajli said, "I did not find an example, for the believer in this life, better than a man on a plank in the sea, imploring, 'O Lord, O Lord', hoping that Allah would save him." Usamah said, "Whenever you see Sufyan ath-Thawri, it is as if you see someone in a ship fearing to drown. One would often hear him say, 'O Lord save me, save me!"

Fatimah bint Abdil Malik, the wife of the Khalifah `Umar ibn `Abdil-Aziz said, "I have never seen a person offering a salah or fasting more than he did, or a person fearing the Lord more than him. After offering Salat-ul-Isha, he would sit down and cry until he becomes sleepy, then he would wake up again and continue crying until sleep overtakes him."

Amir ibn Abdullah was once asked, "How can you tolerate being awake all night, and thirsty in the intense heat of the day?" He replied, "Is it anything more than postponing the food of the day to nighttime, and the sleep of the night to daytime? This is not a big matter." When the night came, he would say, "Remembrance of the heat of hellfire has taken sleepiness from me." And he would not sleep until dawn.

Ahmad ibn Harb said, "I wonder how the one who knows that above him, paradise is being embellished, and below him, the hell-fire is being kindled, and yet sleeps between them!"

Waqi` said, "Al Amash was almost seventy years old and he never missed the first takbirah (for salah in the masjid). I used to visit him frequently for more than two years and never saw him make up for even one rakah."

Abu Hayan related that his father said, "Ar-Rabi` ibn Khuthaym was crippled and used to be carried to the congregational salah. So people told him, "You have an excuse (for not coming)." He said, "I hear 'hayya `alas-salah', the call to salah; so if you can come to it even by crawling, do so", paraphrasing a hadith.

Abull-Mawahib ibn Sarsari said concerning Imam Abul-Qasim ibn Asakir, "I have never seen the like of him, and none had encompassed as many good characteristics as he did concerning his adherence to one way for forty years, making salah in the first row unless he had an excuse, i`tikaf during Ramadan and the ten days of Thul-Hijjah, and the lack of desire to accumulate properties and build houses, as he forbade himself these. He turned away any position of imam or speaker, though they were offered to him, and he devoted himself to enjoin good and forbid evil, and he would not fear anyone in that."
