Hadith 9393 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُعَلَيْهِ وَآلِهِ: مَن ضَمِنَ لي واحِدةً ضَمِنتُ لَهُ أَرْبَعَةَ: يَصِلُ رَحِمَهُ فَيُحِبُّهُ اللَّهُ وَيُوَسِّعُ عَلَيْهِ فِي رِزقِه، وَيَزِيدُ فِي عُمْرِهِ، وَيُدخِلُهُ الجَنَّةَ الَّتِي وَعَدَهُ.
31-93 According to the same documentation, God’s Prophet (S) said, “Whoever guarantees one thing for me, I will guarantee four things for him. If one guarantees to visit his relations of kin, I guarantee that he will be loved by God, his sustenance will increase, his life will be extended, and he will enter the promised Paradise.”
