Imam ‘Ali Ibn Abi Talib (peace be upon him) has said, “By Allah, by Allah, keep the House of your Lord in mind. Do not disregard it as long as you remain (alive) because surely if it is ignored, then He shall not look towards you (with His Mercy).”
It has been narrated from al-Ridha [Imam ‘Ali Ibn Musa] (peace be upon him) that he said, “I have not seen a single thing which makes a person free from want (financially secure) quicker, nor which is more effective in removing poverty, than continuously performing the Hajj (year after year).”
It has been narrated from as-Sadiq [Imam Ja’far Ibn Muhammad] (peace be upon him) who said, “There is no path from the paths of Allah which is greater than Hajj, except when a person comes out with his sword and strives in the way of Allah until he is martyred.”
It has been narrated from Prophet Muhammad (blessings of Allah be upon him and his family) that he said, “A person seeing (visiting) my grave deserves my intercession. And a person who visits me after my death is like a person who visited me during my lifetime.”
It has been narrated from Abi ‘Abdillah [Imam Ja’far Ibn Muhammad as-Sadiq] (peace be upon him) who said, “As long as the Ka’bah is standing, the religion (of al-Islam) will remain standing.”
