Clarifying that it is better to enter Ihram when a person's mount sets off with him, heading towards Makkah, not straight after the two rak'ah
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَنَّأَخْبَرَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ - رضى الله عنهما - قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم رَكِبَ رَاحِلَتَهُ بِذِي الْحُلَيْفَةِ ثُمَّ يُهِلُّ حِينَ تَسْتَوِي بِهِ قَائِمَةً .
'Abdullah b. 'Umar reported: I saw the Messenger of Allah (ﷺ) riding on his camel at Dhu'l-Hulaifa and pronouncing Talbiya as it stood up with him.
