Professor Ansarian:
Islam is an easy religion and practicing all its decrees and ordinances are possible for human being to perform. It is for this reason that on the Day of Resurrection, the excuse of no human being which is based on this notion that the religion was hard is accepted by Allah Almighty. Prophet Muhammad (PBUH) and other infallibles (AS) have repeatedly said in their quotes about the ease and simplicity of the religion of Islam and also emphasized this issue again and again.
Imam Sadeq (AS) is said to have narrated: The wife of Osman bin mazoon, complained of the multiplicity of worship of Uthman, who had troubled his life, complained to the Prophet Mohammad (PBUH) and said: O Messenger of Allah! Osman fasts for days and worships and prays during the night and does not pay attention to me and the needs of my worldly life. Hearing this, the Prophet (pbuh) came out of the house immediately with anxiety and headed the mosque, when he entered the mosque he saw Osman praying. When Osman saw the Messenger of Allah (PBUH), he finished his prayers.
At that time, the Prophet (s) told him: o Osman! Allah has not sent me to abandon getting married and to stay away from worldly adventures, but it has sent me with a moderate, easy and comfortable religion.
