Making up a missed prayer. And it is recommended to hasten to make it up

باب قَضَاءِ الصَّلاَةِ الْفَائِتَةِ وَاسْتِحْبَابِ تَعْجِيلِ قَضَائِهَا ‏‏

Sahih Muslim 684c
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ نَبِيُّ اللَّهِ صلى الله عليه وسلم ‏ ‏ ‏.‏
"‏ مَنْ نَسِيَ صَلاَةً أَوْ نَامَ عَنْهَا فَكَفَّارَتُهَا أَنْ يُصَلِّيَهَا إِذَا ذَكَرَهَا ‏"
Qatada narrated on the authority of Anas b. Malik that the Messenger of Allah (ﷺ) said:

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.
