(6) باب الرُّخْصَةِ فِي أَنْ يُقَالَ لِشَهْرِ رَمَضَانَ رَمَضَانُ
It was narrated from abu Bakrah that the Prophet said;'None of you should say:
'I fasted Ramadan' or 'I prayed Qiyam throughout the whole month."' I do not know whether he dislike self-praise or he said: "Inevitably there will be heedlessness and sleep." (Da 'if) (ES)
