Reward of wrapping a cloth while going to bathroom

1. It was narrated to me by Ali b. Ahmad from his father from his grandfather Ahmad b. Abi Abdillah from his father from Muhammad b. Khalid and Muhammad b. Sinan from al-Muffadhal b. Umar from al-Sadiq عليه السلام who said: “The Almighty Allah will cover with His Own cover one who goes to bathroom wrapping a cloth around himself.”
