Hadith.3401 - Imam Jafar ibn Muhammad Al-Sadiq (as) said to Abu al-Abbas al-Fadl ibn Abd al-Malik: "What has prevented you from performing Hajj?"
He replied: "A guarantee (kafalah) that I undertook."
The Imam (as) said: "What do you have to do with guarantees? Do you not know that guarantees were what destroyed the earlier generations?"
