Ibn ‘Abbas said I heard the Apostle of Allaah ﷺ say When one who is wearing ihram cannot get a lower garment(loin cloth) he may ear trousers and when he cannot get sandals he may wear shoes. Abu Dawud said This is the tradition narrated by the narrators of Makkah. Its narrator from Basrah is Jabir bin Zaid. He mentioned only trousers and omitted the mention of cutting of the shoes.
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ السَّرَاوِيلُ لِمَنْ لاَ يَجِدُ الإِزَارَ وَالْخُفُّ لِمَنْ لاَ يَجِدُ النَّعْلَيْنِ
