Amir al-Sha'bi (may Allah have mercy on him) narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that whenever he greeted Sayyiduna Abdullah bin Ja'far (may Allah be pleased with them both), he would say: "Al-salamu 'alayka ya Ibn Dhi al-Janahayn" (Peace be upon you, O son of the one with two wings).
