Belief
that repentance is an obligation is obligatory, repentance from sins is an
obligation. Allaah سُبحانه وتعالى said:
وَتُوبُوا إِلَى
اللَّهِ جَمِيعًا أَيُّهَا الْمُؤْمِنُونَ لَعَلَّكُمْ تُفْلِحُونَ
'And all of you beg Allâh to forgive you
all, O believers, that you may be successful.'
(An-Nur 24:31)
And
He سُبحانه
وتعالى said:
يَا أَيُّهَا
الَّذِينَ آمَنُوا تُوبُوا إِلَى اللَّهِ تَوْبَةً نَّصُوحًاعَسَى رَبُّكُمْ أَن
يُكَفِّرَ عَنكُمْ
"O you who believe! Turn to Allâh with
sincere repentance! It may be that your Lord will remit from you your sins.."
(At-Tahrim 66:8)
And
He سُبحانه
وتعالى said:
وَمَن لَّمْ
يَتُبْ فَأُوْلَئِكَ هُمُ الظَّالِمُونَ
"And whosoever does not repent, then
such are indeed Zâlimûn (wrong-doers, etc.)."
(Al-Hujurat 49:11)
Therefore
it is obligatory for the Muslim to repent from his sins and from his evil deeds
and it is obligatory that he does not continue upon them or commence upon them
or that he is negligent with regards to sins, and he says; ‘this is easy.' Do
not be negligent with it for it is from the sins, rather hasten with
repentance.
