" Abu[Ar-Raddad] Al-Laithi complained(of an illness). So 'Abdur-Rahman bin 'Awf visited him. He said: 'The best of you, and the most apt to maintain good relations, as far as I know, is Abu Muhammad('Abdur-Rahman bin 'Awf). So 'Abdur-Rahman bin 'Awf' said: 'I heard the Messenger of Allah saying : "Allah, Most Blessed and Most High, said: 'I am Allah, and I am Ar-Rahman. I created the Rahim(womb), and named it after My Name. So whoever keeps good relations with it, I keep good relation with him, and whoever severs it, I am finished with him.'" (Using translation from Tirmidhī 1907)
أَبُو الرَّدَّادِ خَيْرُهُمْ وَأَوْصَلُهُمْ مَا عَلِمْتُ أَبَا مُحَمَّدٍ فَقَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ قَالَ اللهُ ﷻ أَنَا اللهُ وَأَنَا الرَّحْمَنُ خَلَقْتُ الرَّحِمَ وَشَقَقْتُ لَهَا مِنَ اسْمِي فَمَنْ وَصَلَهَا وَصَلْتُهُ وَمَنْ قَطَعَهَا بَتَتُّهُ
