Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) forbade qaza’. I asked: What is meant by qaza’? He said: Qaza’ is when part of a child’s head is shaved and part is left unshaven.

Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) saw a child whose head had some hair shaved and some left unshaved. The Prophet (peace and blessings be upon him) said: Shave the entire head or leave the entire head.

Sayyiduna Abdullah bin Ja'far (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) (at the time of the martyrdom of Sayyiduna Ja'far, may Allah be pleased with him) did not come to us for three days, then he (peace and blessings be upon him) came and said to us: Do not weep over my brother Ja'far after today or tomorrow. Call my nephews. So we were brought, and it seemed as if we were chicks. He (peace and blessings be upon him) said: Call the barber. So the barber was brought, then he shaved our heads.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: When any of you yawns, he should restrain it as much as possible, because the devil enters the mouth.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Indeed, Allah Almighty likes sneezing and dislikes yawning. When a person sneezes and says "Alhamdulillah," it is the right of the one who hears him to say "Yarhamukallah." And when any one of you yawns, he should try his best to restrain it and not make the sound "aah," because when any one of you opens his mouth, Satan laughs at him. In the narration of Hajjaj, it is mentioned: As for yawning, it is from Satan.

It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Yawning is from the devil, so when any of you feels like yawning, he should restrain it as much as possible.

Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that when the Noble Prophet (peace and blessings be upon him) sneezed, he would place his garment or his hand on his forehead and would lower his voice.
