“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)
قَالَ رَسُولُ اللهِ ﷺ عَلَيْكُمْ بِقِيَامِ اللَّيْلِ؛ فَإِنَّهُ دَأَبُ الصَّالِحِينَ قَبْلَكُمْ وَإِنَّ قِيَامَ اللَّيْلِ قُرْبَةٌ إِلَى اللهِ تَعَالَى وَتَكْفِيرٌ لِلسَّيِّئَاتِ وَمَنْهَاةٌ عَنِ الْإِثْمِ وَمَطْرَدَةٌ لِلدَّاءِ عَنِ الْجَسَدِ
