وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ لِعَلِيٍّ عَلَيْهِ اَلسَّلاَمُ: «يَا عَلِيُّ مَنْ زَارَنِي فِي حَيَاتِي أَوْ بَعْدَ مَمَاتِي أَوْ زَارَكَ فِي حَيَاتِكَ أَوْ بَعْدَ مَمَاتِكَ أَوْ زَارَ اِبْنَيْكَ فِي حَيَاتِهِمَا أَوْ بَعْدَ مَمَاتِهِمَا ضَمِنْتُ لَهُ يَوْمَ اَلْقِيَامَةِ أَنْ أُخَلِّصَهُ مِنْ أَهْوَالِهَا وَ شَدَائِدِهَا حَتَّى أُصَيِّرَهُ مَعِي فِي دَرَجَتِي ».
The Messenger of Allah (swt), peace be upon him and his family, said to Imam Ali ibn Abi Talib (a.s), peace be upon him: "O Ali, whoever visits me during my lifetime or after my death, or visits you during your lifetime or after your death, or visits your two sons during their lifetimes or after their deaths, I guarantee for them on the Day of Judgment that I will deliver them from its terrors and hardships until I bring them to be with me in my rank."
