فَقُلْتُ ٱسْتَغْفِرُوا۟ رَبَّكُمْ إِنَّهُۥ كَانَ غَفَّارًۭا ﴿10﴾ يُرْسِلِ ٱلسَّمَآءَ عَلَيْكُم مِّدْرَارًۭا ﴿11﴾ وَيُمْدِدْكُم بِأَمْوَٰلٍۢ وَبَنِينَ وَيَجْعَل لَّكُمْ جَنَّٰتٍۢ وَيَجْعَل لَّكُمْ أَنْهَٰرًۭا ﴿12﴾
(10)And said, 'Ask forgiveness of your Lord. Indeed, He is ever a Perpetual Forgiver. (11)He will send [rain from] the sky upon you in [continuing] showers (12)And give you increase in wealth and children and provide for you gardens and provide for you rivers.
وَأَنِ ٱسْتَغْفِرُوا۟ رَبَّكُمْ ثُمَّ تُوبُوٓا۟ إِلَيْهِ يُمَتِّعْكُم مَّتَٰعًا حَسَنًا إِلَىٰٓ أَجَلٍۢ مُّسَمًّۭى وَيُؤْتِ كُلَّ ذِى فَضْلٍۢ فَضْلَهُۥ ۖ وَإِن تَوَلَّوْا۟ فَإِنِّىٓ أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍۢ كَبِيرٍ ﴿3﴾
(3)And [saying], "Seek forgiveness of your Lord and repent to Him, [and] He will let you enjoy a good provision for a specified term and give every doer of favor his favor. But if you turn away, then indeed, I fear for you the punishment of a great Day.
وَيَٰقَوْمِ ٱسْتَغْفِرُوا۟ رَبَّكُمْ ثُمَّ تُوبُوٓا۟ إِلَيْهِ يُرْسِلِ ٱلسَّمَآءَ عَلَيْكُم مِّدْرَارًۭا وَيَزِدْكُمْ قُوَّةً إِلَىٰ قُوَّتِكُمْ وَلَا تَتَوَلَّوْا۟ مُجْرِمِينَ ﴿52﴾
(52)And O my people, ask forgiveness of your Lord and then repent to Him. He will send [rain from] the sky upon you in showers and increase you in strength [added] to your strength. And do not turn away, [being] criminals."
وَمَا كَانَ ٱللَّهُ لِيُعَذِّبَهُمْ وَأَنتَ فِيهِمْ ۚ وَمَا كَانَ ٱللَّهُ مُعَذِّبَهُمْ وَهُمْ يَسْتَغْفِرُونَ ﴿33﴾
(33)But Allah would not punish them while you, [O Muhammad], are among them, and Allah would not punish them while they seek forgiveness.
ٱلصَّٰبِرِينَ وَٱلصَّٰدِقِينَ وَٱلْقَٰنِتِينَ وَٱلْمُنفِقِينَ وَٱلْمُسْتَغْفِرِينَ بِٱلْأَسْحَارِ ﴿17﴾
(17)The patient, the true, the obedient, those who spend [in the way of Allah], and those who seek forgiveness before dawn.
وَبِٱلْأَسْحَارِ هُمْ يَسْتَغْفِرُونَ ﴿18﴾
(18)And in the hours before dawn they would ask forgiveness,
فَسَبِّحْ بِحَمْدِ رَبِّكَ وَٱسْتَغْفِرْهُ ۚ إِنَّهُۥ كَانَ تَوَّابًۢا ﴿3﴾
(3)Then exalt [Him] with praise of your Lord and ask forgiveness of Him. Indeed, He is ever Accepting of repentance.
وَٱسْتَغْفِرِ ٱللَّهَ ۖ إِنَّ ٱللَّهَ كَانَ غَفُورًۭا رَّحِيمًۭا ﴿106﴾
(106)And seek forgiveness of Allah. Indeed, Allah is ever Forgiving and Merciful.
