It is narrated from Amir that whenever Sayyiduna Ibn Umar (may Allah be pleased with them both) greeted Sayyiduna Abdullah bin Ja'far (may Allah be pleased with him), he would say: 'As-salamu alayka ya Ibn Dhi al-Janahayn' (Peace be upon you, O son of the one with two wings). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it; and I have deferred the virtues of Ja'far bin Abi Talib (may Allah be pleased with him) so as to mention them in the chapter on the virtues of all the Companions.
