“Ishaq bin Mansur narrated to us, from Isra’il” with this (Another chain) Bilal narrated that the Messenger of Allah ﷺ said: “Hold fast to Qiyam al-Lail, for it is the practice of the righteous before you, and indeed Qiyam al-Lail is a means of nearness to Allah, a means of prevention from sin, an expiation for bad deeds, and a barrier for the body against disease.” (Using translation from Tirmidhī 3549)
عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ عَلَيْكُمْ بِقِيَامِ اللَّيْلِ فَإِنَّهُ دَأَبُ الصَّالِحِينَ قَبْلَكُمْ وَقُرْبَةٌ إِلَى اللهِ وَتَكْفِيرٌ لِلسَّيِّئَاتِ وَمَنْهَاةٌ عَنِ الْإِثْمِ وَمَطْرَدَةٌ لِلدَّاءِ عَنِ الْجَسَدِ لَفْظُ حَدِيثِ أَبِي عَبْدِ اللهِ وَفِي رِوَايَةِ الْقَطَّانِ وَإِنَّ قِيَامَ اللَّيْلِ قُرْبَةٌ إِلَى اللهِ تَعَالَى
