(V.2:124) It is said that those commands were many. Some of them are as follows:
(A) To invite mankind to the Tauhîd (Islamic Monotheism).
(B) To show mankind the Manâsik (See V.2:128).
(C) To practise the characteristics of Al-Fitrah:
Narrated Abu Hurairah رضي الله عنه: I heard the Prophet صلى الله عليه وسلم saying:
Five practices are characteristic of Al-Fitrah:
(1) Circumcision.
(2) Shaving the pubic hair.
(3) Cutting the moustaches short.
(4) Clipping the nails.
(5) and depilating the hair of the armpits.
(Sahih Al-Bukhari, Hadith No.779, Vol.7)
Narrated Ibn Umar رضي الله عنهما Allâh’s Messenger صلى الله عليه وسلم said: "Cut the moustaches short and leave the beard (as it is)." (Sahih Al-Bukhari, Hadith No.781, Vol.7)
(D) It is also mentioned that Ibrâhîm عليه السلام was put to test: (1) When he عليه السلام was thrown in the Fire. (2) When he عليه السلام was ordered to slaughter his son. (Tafsir Ibn Kathir)
