عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَتْ نِعَالُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَهَا قِبَالَانِ
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the sandals of the Messenger of Allah, peace and blessings be upon him, had two straps at the front, with which he would tie the thong.
