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)
