BE CONSISTENT H 154 "Of religious actions Allah likes that which one practices continuously. A person who misses his voluntary prayer or a portion of it at night because of sleep will be credited with the same merit if he makes up for it any time between the dawn and mid-day prayer." R 154 The Mother of Believers, Lady Ayesha who related the Prophet, praise and peace be upon him, said this. Muslim with a chain up to Omar son of Khattab who related that the Prophet, praise and peace be upon him, said this.
153- وَأَمَّا الأَحاديث فمنها : حديث عائشة : وَكَانَ أَحَبُّ الدِّين إِلَيْهِ مَا دَاوَمَ صَاحِبُهُ عَلَيهِ . وَقَدْ سَبَقَ في البَاب قَبْلَهُ وعن عمر بن الخطاب رضي الله عنه ، قَالَ : قَالَ رَسُول الله صلى الله عليه وآله وسلم : "مَنْ نَامَ عَنْ حِزْبهِ مِنَ اللَّيلِ ، أَوْ عَنْ شَيءٍ مِنْهُ ، فَقَرَأَهُ مَا بَيْنَ صَلاةِ الفَجْرِ وَصَلاةِ الظُّهْرِ ، كُتِبَ لَهُ كَأَنَّمَا قَرَأَهُ مِنَ اللَّيلِ" رواه مسلم .
