Salim reported that when it was said to Ibn 'Umar (Allah be pleased with them) that the state of Ihram (commences from)a al-Baida' he said:Al-Baida', you attribute lie about it to the Messenger of Allah (ﷺ). And the Messenger of Allah (ﷺ) did not enter upon the state of Ihram but near the tree when his camel stood up with him.
وَحَدَّثَنَاهُ قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ مُوسَى بْنِ، عُقْبَةَ عَنْ سَالِمٍ، قَالَ كَانَ ابْنُ عُمَرَ - رضى الله عنهما - إِذَا قِيلَ لَهُ الإِحْرَامُ مِنَ الْبَيْدَاءِ قَالَ الْبَيْدَاءُ الَّتِي تَكْذِبُونَ فِيهَا عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم مَا أَهَلَّ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلاَّ مِنْ عِنْدِ الشَّجَرَةِ حِينَ قَامَ بِهِ بَعِيرُهُ .
