A man whose father calls him while he is praying

It is narrated from Muhammad bin al-Munkadir that the Messenger of Allah (peace and blessings be upon him) said: "When your mother calls you while you are in prayer, answer her; and if your father calls you, do not answer him."

Makhul said: When your mother calls you while you are in prayer, answer her; and if your father calls you, do not answer him until you have finished the prayer.

Al-Awwam said: I asked Mujahid: If the prayer is started (with the iqamah) and my mother calls me, what should I do? He said: Answer your mother.

Sayyiduna Umar (may Allah be pleased with him) disliked that a man should pray with fetters on his feet.
