My father narrated from Mohammad bin Husain , from Mohammad bin Hasan Al-Saffar, from Ahmad bin Mohammad, from his father, from Abdullah bin Al-Moghira and Mohammad bin Yahya Al-Khath’ami, from Mohammad bin Bohloul Al-Abdi, from JAAFAR BIN MOHAMMAD (ASWS), FROM HIS FATHER MOHAMMAD BIN ALI (ASWS) , FROM HIS FATHER, FROM HIS FATHER HUSAIN BIN ALI (ASWS) , who said:
The MESSENGER OF ALLAH (SWT) said that on the night of Me’raaj, when he went up and passed the gates of light, ALLAH (SWT) talked to him, and said:
O MOHAMMAD (SAWW)! Convey My Salaam to ALI BIN ABI TALEB (ASWS), and inform him that he is My decisive proof on all creatures after you. I pour the rain of My blessings on My slaves through him; I keep everything evil away from them through him; and he is My decisive proof on them when they meet Me.
So they should follow his commands, obey his orders, and abstain when he abstains. If they do so, I will sit them next to Me and I will allow them to enter My Paradise. If they do not, I will put them with the worst of My enemies in Hell and I will not care.
