Whenever Ibn 'Umar (RAA) came to Makkah he would spend the night at Dhi Tuwa valley (near Makkah), and in the morning he would bathe. ‘Ibn 'Umar used to say that this is what the Messenger of Allah (ﷺ), used to do.’ Agreed upon.

وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا: { أَنَّهُ كَانَ لَا يَقْدُمُ مَكَّةَ إِلَّا بَاتَ بِذِي طُوَى حَتَّى يُصْبِحَ وَيَغْتَسِلَ, وَيَذْكُرُ ذَلِكَ عِنْدَ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-} مُتَّفَقٌ عَلَيْهِ [1]‏ .‏
