Ibn Umar (Allah be pleased with him) reported that Allah's Messenger (ﷺ) ﷺ) spent the night at Dhi Tuwa till it was dawn and then entered Mecca. 'Abdullah (b. 'Umar) himself did like it. And in the narration transmitted by Ibn Sa'ld (the words are):

Until he obrerved the dawn prayer. Yahya (another narrator) said: Until it was dawn.

حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، وَعُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا يَحْيَى، - وَهُوَ الْقَطَّانُ - عَنْ عُبَيْدِ اللَّهِ، أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم بَاتَ بِذِي طَوًى حَتَّى أَصْبَحَ ثُمَّ دَخَلَ مَكَّةَ ‏.‏ قَالَ وَكَانَ عَبْدُ اللَّهِ يَفْعَلُ ذَلِكَ ‏.‏ وَفِي رِوَايَةِ ابْنِ سَعِيدٍ حَتَّى صَلَّى الصُّبْحَ ‏.‏ قَالَ يَحْيَى أَوْ قَالَ حَتَّى أَصْبَحَ ‏.‏
