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
