Prayer
What one says when one gets up during the night - Section 2
وَعَنْ مُعَاذِ بْنِ جَبَلٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا مِنْ مُسْلِمٍ يَبِيتُ عَلَى ذِكْرٍ طَاهِرًا فَيَتَعَارَّ مِنَ اللَّيْل فَيسْأَل اللَّهُ خَيْرًا إِلَّا أَعْطَاهُ اللَّهُ إِيَّاهُ» . رَوَاهُ أَحْمد وَأَبُو دَاوُد
Mu'adh b. Jabal reported God’s Messenger as saying, “If any Muslim goes to bed in a state of purity making mention of God, then is disturbed [from sleep] during the night and asks God for good, God will give it to him.” Ahmad and Abu Dawud transmitted it.
