When a person who is sexually impure wants to have intercourse again, he should perform ablution

It was narrated that Abu Sa'eed said:
"The Messenger of Allah said: 'If anyone of you has intercourse with his wife, then he wants to do it again, let him perform ablution.'"

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْمَلِكِ بْنِ أَبِي الشَّوَارِبِ، حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ زِيَادٍ، حَدَّثَنَا عَاصِمٌ الأَحْوَلُ، عَنْ أَبِي الْمُتَوَكِّلِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " إِذَا أَتَى أَحَدُكُمْ أَهْلَهُ ثُمَّ أَرَادَ أَنْ يَعُودَ فَلْيَتَوَضَّأْ " .
