وَحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ الأَنْصَارِيَّ، سُئِلَ عَنِ الْمَسْحِ، عَلَى الْعِمَامَةِ فَقَالَ لاَ حَتَّى يُمْسَحَ الشَّعْرُ بِالْمَاءِ ‏.‏

Yahya related to me from Malik that he had heard that Jabir ibnAbdullah al-Ansari was asked about wiping over a turban. He said, "Notunless you have wiped over your hair with water." Translation Not Available
