On the authority of Abū Mūsa al-Ash’ari (رضي الله عنه) who quoted Allāh’s Messenger (ﷺ) as saying,
إِن الله يبْسُطُ يدهُ بِاللَّيْلِ ليتُوب
مُسيءُ النَّهَارِ، وَيبْسُطُ يَدهُ بالنَّهَارِ ليَتُوبَ مُسِيءُ اللَّيْلِ حتَّى
تَطْلُعَ الشَّمْسُ مِن مغْرِبِها
رواه مسلم: ٢٧٥٩
Allāh
stretches out His Hand during the night, so that people may repent for their
shortcomings committed during the day. He also stretches out His Hand during
the day, so that the sinners may repent for the sins committed during the
night. Until the sun rises in the west(1). (Muslim: 2759).
1. The
rising of the sun in the west is a major portent of the Day of
Resurrection.(Translator)
