The weaknesses were Buddhist monks had no families, while Muslims believe in family relations. In Buddhism, everyone is more the same and Islam is more patriarchal.
Buddhism and Islam are both devoted to their religion, both tolerant of faiths. Both believe in charity. Sufis were more "meditative" similar to Buddhists.
Islam believed in a god, while Buddhists believe in themselves w/o a god. Muslims believe in patriarchy while Buddhists believe in equality. Reincarnation VS. Heaven.
