Also inform them that in a fit of fury they must not invite my wrath and should not hold my friends low in their sight, because some of My chastisements are such which can never be tolerated by any of My creations. It is recorded in reliable sources from Imam al-Ridha that Allah directed one of his Messengers through revelation that when “My slaves obey Me I become pleased with them and when I become pleased with them I shower My Blessing on them and My blessings are endless.

And when they disobey me then I become angry and when I become angry with them I curse them which remains effective for them for seven generations.” It is narrated from Imam as-Sadiq that a Prophet complained to Allah about his weakness. It was revealed to him that he should cook meat with butter-milk and eat it as it strengthens the physique. When another Messenger complained of impotency (sexual weakness) he was ordered to eat porridge.

Yet another Prophet complained about dearth of progeny and shortage of sons it was revealed to him that he should eat meat with eggs. Another reliable tradition says a Prophet complained of harshness of heart and dearth of weeping (kindness) he was ordained (through revelation) to eat masoor (lentil). He continued eating it which resulted in his becoming soft-hearted and he began to weep more (for fear of Allah).

Another messenger complained of gloominess and excessive grief and Allah ordained him to eat grapes. It is recorded with authentic chains from Imam as-Sadiq that a group from the past peoples asked their Prophet to pray to Allah for lifting up death from them. He prayed and Allah accepted his prayer.

Consequently their number multiplied so much that they had no houses to live and their progeny increased so much that right from daybreak everybody had to be busy feeding, cleaning, bathing and even taking their great grandfathers to the latrine. They were so busy until night they would not get time to earn their livelihood. Thus their lives became full of hardships. Finally they asked their Prophet to pray to Allah to revert them to their earlier condition and so it happened.

In another authentic hadith it is mentioned that Allah did never pour His chastisement on any of the past people but on Wednesday which used to fall in the middle of the month. It is mentioned in yet another reliable tradition that Allah revealed to a Prophet that good behavior melts sins as the suns melts ice.
