Sacrifice and deduction of the Umar

It is narrated from Huzaifah bin Usaid that: “Abu Bakr and Umar, fearing that lest the sacrifice should be attributed to someone else, did not offer sacrifice from their families; but my family learnt about Sunnah of Prophet (s.a.w.a.) and compelled me to take the trouble to present sacrifice from their side.”

[Al-Mojamul Kabeer, Tibrani, [3/182, H. 3058].

Shafei says in his Al-Umm:  “It has reached us that Abu Bakr and Umar refrained from sacrificing, lest people follow them thinking that it was obligatory.” “It is narrated from Shobi that Abu Bakr and Umar participated in rituals of Hajj, but did not slaughter animals.”
