It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Paradise boasted over Hell and said: 'I am better than you.' Hell replied: 'Rather, I am better than you.' Paradise then asked it by way of inquiry: 'And on what basis?' Hell said: 'Because in me are the great tyrants, Nimrod and Pharaoh.' So Paradise fell silent, and Allah Almighty revealed to it: 'Do not feel humbled; I will surely adorn your two corners with Sayyiduna al-Hasan and Sayyiduna al-Husayn (may Allah be pleased with them both).' So Paradise (on hearing this) swayed just as a bride sways gracefully in her bridal chamber."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Mukhtar bin Fulful (may Allah have mercy on him) except Sulayman bin al-Mughirah (may Allah have mercy on him), and Abbad bin Suhayb (may Allah have mercy on him) is alone in narrating it."
