============

opposite is :

"Whosoever turns away from My remembrance, his life will be made tight and narrow on the Day of Resurrection We shall raise him blind"
Quran (Surah 20: Verse 124)

Ta-Ha

But he who turneth away from remembrance of Me, his will be a narrow life, and I shall bring him blind to the assembly on the Day of Resurrection. (124) He will say: My Lord! Wherefor hast Thou gathered me (hither) blind, when I was wont to see? (125) He will say: So (it must be). Our revelations came unto thee but thou didst forget them. In like manner thou art forgotten this Day. (126)

Ta-Ha

"But whosoever turns away from My Reminder (i.e. neither believes in this Qur'ân nor acts on its teachings) verily, for him is a life of hardship, and We shall raise him up blind on the Day of Resurrection." (124) He will say:"O my Lord! Why have you raised me up blind, while I had sight (before)." (125) (Allâh) will say: "Like this, Our Ayât (proofs, evidences, verses, lessons, signs, revelations, etc.) came unto you, but you disregarded them (i.e. you left them, did not think deeply in them, and you turned away from them), and so this Day, you will be neglected (in the Hell-fire, away from Allâh's Mercy)." (126) And thus do We requite him who transgresses beyond bounds [i.e. commits the great sins and disobeys his Lord (Allâh) and believes not in His Messengers, and His revealed Books, like this Qur'ân, etc.], and believes not in the Ayât (proofs, evidences, verses, lessons, signs, revelations) of his Lord, and the torment of the Hereafter is far more severe and more lasting. (127) Is it not a guidance for them (to know) how many generations We have destroyed before them, in whose dwellings they walk? Verily, in this are signs indeed for men of understanding. (128)
