Hadith 7:103
Abu Musa reported God’s messenger as saying, "God stretches out His hand at night that those who have done evil during the day may repent and stretches out His hand in the day-time that those who have done evil during the night may repent, until [the time when] the sun rises in the west." Muslim transmitted it.
وَعَنْ أَبِي مُوسَى رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ اللَّهَ يَبْسُطُ يَدَهُ بِاللَّيْلِ لِيَتُوبَ مُسِيءُ النَّهَارِ وَيَبْسُطُ يَدَهُ بِالنَّهَارِ لِيَتُوبَ مُسِيءُ اللَّيْلِ حَتَّى تَطْلُعَ الشَّمْسُ مِنْ مَغْرِبِهَا» . رَوَاهُ مُسْلِمٌ
