Iblis (Shaytan) Cried Out Loudly Four Times

It is said that Iblis {Shaytan} cried out loudly four times.

1} Firstly, when Allah declared him to be cursed,

2} Secondly, when he was thrown out,

3} Thirdly, when the Prophet {Peace and Blessings of Allah be upon him} was born and

4} Fourthly, when Surah al-Fatiha was revealed."

أن إبليس رن أربع رنات حين لعن وحين أهبط وحين ولد رسول الله صلى الله عليه وسلم وحين أنزلت الفاتحة
