Al-Matalib al-'Aliyah 3885 — The virtues of Umar bin al-Khattab

It is narrated from Salim bin Abi al-Ja'd (may Allah have mercy on him) that the people of Najran came to Sayyiduna Ali (may Allah be pleased with him) and said: "We ask you to write (a permit) for us with your own blessed hand and to intercede for us with your tongue, that you send us back (to our homeland)." At this Sayyiduna Ali (may Allah be pleased with him) said: "Sayyiduna Umar (may Allah be pleased with him) was most upright and sound of judgement in managing his affairs; if it had ever been possible to object to his decision on any occasion, he would certainly have been objected to on this day (that is, his decision was firm and correct in every respect and cannot be changed)."
Imam Musaddad (may Allah have mercy on him) narrated this report; Abdullah bin Dawud transmitted it from al-A'mash, and he from Salim bin Abi al-Ja'd.
