إِنَّنِىٓ أَنَا ٱللَّهُ لَآ إِلَٰهَ إِلَّآ أَنَا۠ فَٱعْبُدْنِى وَأَقِمِ ٱلصَّلَوٰةَ لِذِكْرِىٓ ﴿١٤﴾
Hakika Mimi ndiye Mwenyezi Mungu. Hapana mungu ila Mimi tu. Basi niabudu Mimi, na ushike Sala kwa ajili ya kunikumbuka Mimi.
Prayer (Salah)
A person who sleeps through a prayer or forgets it prays it as soon as he wakes or remembers. The Prophet ﷺ said that its only expiation is to pray it, then recited: establish prayer for My remembrance (20:14).
The four Sunni schools agree on the main ruling above and differ in these points. No school is preferred here.
إِنَّنِىٓ أَنَا ٱللَّهُ لَآ إِلَٰهَ إِلَّآ أَنَا۠ فَٱعْبُدْنِى وَأَقِمِ ٱلصَّلَوٰةَ لِذِكْرِىٓ ﴿١٤﴾
Hakika Mimi ndiye Mwenyezi Mungu. Hapana mungu ila Mimi tu. Basi niabudu Mimi, na ushike Sala kwa ajili ya kunikumbuka Mimi.
The point of the hadith: Whoever forgets a prayer should pray it when he remembers. There is no expiation except that.
حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ نَسِيَ صَلاَةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا لاَ كَفَّارَةَ لَهَا إِلاَّ ذَلِكَ " . قَالَ قَتَادَةُ وَأَقِمِ الصَّلاَةَ لِذِكْرِي .
