Muwatta Imam Malik (Riwayat Yahya)

Yahya said: Imam Malik, may Allah have mercy on him, was asked about a person who performed ablution and, out of forgetfulness, washed his face before rinsing his mouth, or washed his hands before washing his face. Imam Malik, may Allah have mercy on him, said: Whoever washed his face before rinsing his mouth should rinse his mouth and not wash his face again. But whoever washed his hands before washing his face should wash his face and then wash his hands again, so that the washing of the hands comes after the washing of the face, as long as the one performing ablution is still in his place or near it.
