"It has not been authentically reported from the Prophet (sallallaahu ?alayhi wa sallam) that he used to raise his hands with the takbeers of ?Eed.  However Ibnul-Qayyim said: ??Ibn ?Umar with his adherent following of the Sunnah used to raise his hands with each takbeer.??  I say: The best guidance is the guidance of Muhammad (sallallaahu ?alayhi wa sallam). Our Shaykh - al-Albaanee said in Tamaamul-Minnah (p. 348): ??That fact that it is reported from ?Umar and his son does not make it a Sunnah, especially when the reports from ?Umar and his son are not authentic. As for what is reported from ?Umar then it is transmitted by al-Bayhaqee with a weak chain of narration and as for what is reported for his son, then as of yet I have not come across it.?? Our Shaykh also says: in Ahkaamul-Janaa?iz (p. 148) in a matter similar to this: ??He who thinks that he - Ibn ?Umar - would not do this except by permission from the Prophet (sallallaahu ?alayhi wa sallam) then he should raise his hands.??
