Since it has been proved according to your views that they preferred, in the incident of Usamah's regiment, the interest of Islam, following their own views rather than those of the Prophet as embedded in his statements, then why don't you likewise say that they preferred in the issue of caliphate to follow their own views regarding what is good for Islam to those of the Prophet (pbuh) as stated in his Ghadir hadith and the like?

You have found excuses for those who cast doubts about Usamah's appointment, saying that they did so only because of his young age and their being middle-aged and old, and that old folks are naturally made to resent taking orders from the young; so, why don't you apply the same argument to those who did not follow the Ghadir texts appointing Ali (as), who was a young man, to take charge of middle-aged and elderly companions, who considered him young at the time when the Messenger of Allah, peace be upon him and his progeny, died just as they considered Usamah young when the Prophet (pbuh) appointed him as their commander in that regiment?

What a big difference between caliphate and the leadership of a regiment! If their nature refused to accept the leadership of a youth in commanding one regiment, they were more liable to refuse the lifetime leadership of a youth in all religious and secular matters.

But your argument that middle-aged and elderly folks naturally resent receiving orders from the young is rejected if you apply it to all matters, since those whose faith is strong among elderly believers certainly do not resent being commanded by Allah and His Messenger to take orders from a youth, or in any other matter. "Nay!

By thy Lord, they shall never truly believe till they totally accept your judgment in all their disputes, then they do not feel any hardship in accepting your judgment, submitting thereto wholeheartedly (Qur'an, 4:65)." "Whatever the Messenger grants you, take it, and abstain from whatever he forbids you (Qur'an, 59:7)." II Al-Shahristani's Hadith is Documented.
