April 7

In this day no less than seventy thousand people make pilgrimage every year to the holy House of God in compliance with the bidding of the Apostle of God; while He Himself Who ordained this ordinance took refuge for seven years in the mountains of Mecca. [1] And this notwithstanding that the One Who enjoined this commandment is far greater than the commandment itself. Hence all this people who at this time go on pilgrimage do not do so with true understanding, otherwise in this Day of His Return which is mightier than His former Dispensation, they would have followed His commandment. But now behold what hath happened. People who profess belief in His former religion, who in the daytime and in the night season bow down in worship in His Name, have assigned Him to a dwelling place in a mountain, while each one of them would regard attaining recognition of Him as an honour.

[1] For no less than seven years no one acknowledged His Teachings except Imám ‘Ali, His son-in-law.
