Abu Ghatfan (may Allah have mercy on him) says that I went to Abdullah bin Abbas (may Allah be pleased with them), and found him performing ablution. He rinsed his mouth, put water in his nose, and said: The Noble Prophet (peace and blessings be upon him) said: Clean your nose thoroughly two or three times.
