If any one forgets a prayer or oversleeps, he should observe it when he remembers it ; there is no expiation for it except that.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ نَسِيَ صَلاَةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا لاَ كَفَّارَةَ لَهَا إِلاَّ ذَلِكَ  

The Prophet ﷺ said: If anyone oversleeps and misses the witr, or forgets it, he should pray when he remembers.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ نَامَ عَنْ وِتْرِهِ أَوْ نَسِيَهُ فَلْيُصَلِّهِ إِذَا ذَكَرَهُ  

[Machine] The Messenger of Allah ﷺ said: "Whoever forgets a prayer or sleeps through it, then the atonement for it is to pray it when they remember it."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ نَسِيَ صَلَاةً أَوْ نَامَ عَنْهَا فَإِنَّ كَفَّارَتَهَا أَنْ يُصَلِّيَهَا إِذَا ذَكَرَهَا  

[Machine] If you missed a prayer or slept through it, then its expiation is to pray it when you remember it. Yazid said: And its expiation is to repent for it.  

قَالَ رَسُولُ اللهِ ﷺ مَنْ نَسِيَ صَلَاةً أَوْ نَامَ عَنْهَا فَإِنَّمَا كَفَّارَتُهَا أَنْ يُصَلِّيَهَا إِذَا ذَكَرَهَا قَالَيَزِيدُ فَكَفَّارَتُهَا أَنْ  

The Prophet ﷺ said: If anyone oversleeps and misses the witr, or forgets it, he should pray when he remembers. (Using translation from Abū Dāʾūd 1431)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ نَسِيَ الْوَتْرَ أَوْ نَامَ عَنْهَا فَلْيُصَلِّهَا إِذَا ذَكَرَهَا أَوْ إِذَا أَصْبَحَ  

"Whoever forgets a prayer, let him pray it when he remembers it, for Allah says: and perform the Salah for My remembrance." [1] [1] Ta-Ha 20:14. (Using translation from Nasāʾī 619)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ نَسِيَ صَلَاةً أَوْ نَامَ عَنْهَا فَلْيُصَلِّهَا إِذَا ذَكَرَهَا إِنَّ اللَّهَ تَعَالَى يَقُولُ {وَأَقِمِ الصَّلَاةَ لِذِكْرِي} [طه 14]  

The Prophet ﷺ said, "If anyone forgets a prayer he should pray that prayer when he remembers it. There is no expiation except to pray the same." Then he recited: "Establish prayer for My (i.e. Allah's) remembrance." (20.14). (Using translation from Bukhārī 597)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ نَسِيَ صَلَاةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا لَا كَفَّارَةَ لَهَا إِلَّا ذَلِكَ»  

[Machine] On the authority of the Prophet ﷺ who said, "Whoever forgets a prayer or oversleeps it should perform it as soon as they remember."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ «مَنْ نَسِيَ صَلَاةً أَوْ نَامَ عَنْهَا فَلْيُصَلِّهَا إِذَا ذَكَرَهَا»  

He who forgets the prayer, or he slept (and it was omitted), its expiation is (only) that he should observe it when he remembers it. (Using translation from Muslim 684c)   

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ نَسِيَ صَلَاةً أَوْ نَامَ عَنْهَا فَكَفَّارَتُهَا أَنْ يُصَلِّيَهَا إِذَا ذَكَرَهَا»  

"مَنْ نَسِيَ صَلاةً فَلْيُصَلِهَا إِذَا ذَكرَهَا، لا كَفارَةَ لَهُ إِلا ذَلِكَ".  

"مَنْ نَسِيَ صَلاةً أوْ نَامَ عَنْهَا، فَكَفَّارَتُهَا أنْ يُصَلِّيَهَا إذَا ذَكرَهَا".
