(39) باب ثَوَابِ مَنْ قَامَ رَمَضَانَ وَصَامَهُ إِيمَانًا وَاحْتِسَابًا وَالاِخْتِلاَفِ عَلَى الزُّهْرِيِّ فِي الْخَبَرِ فِي ذَلِكَ
It was narrated from Abu Hurairah that the Messenger of Allah said:
"Whoever spends the nights of Ramadan n prayer (Qiyam) out of faith and in the hope of reward, he will be forgiven his previous sins." '
