Objections were raised saying that the senior companions were opposed to being placed under the command of Usama who was a young man. Many argued that on earlier occasions, the Prophet (s) had placed the very same companions under the charge of Ali (a.s) who was the youngest among them. However, a foundation was laid for a demur and claim that the leader should only be an older member and not any youngster.
Unable to collect men around him, Usama twice met the Prophet (s)who became angry at his orders being disobeyed and he insisted that Usama should immediately collect all the men and proceed on the expedition without further delay. Books of history are full of reports as to how Usama tried to collect the men for the expedition and how they refused to assemble under his leadership and how the companions of the Prophet (s) disobeyed the ailing Prophet (s).
Whenever the Prophet (s) called for Ali (a.s), each of these two women would suggest that her father might be called instead of Ali (a.s), but the Prophet (s) insisted on Ali (a.s), with whom he conferred for a long time.
The Prophet (s) said, “God’s curse upon those who demurred in joining the army of Usama”
