A similar hadith is narrated from Abdullah bin Amr bin Al-As through this chain as well, but in it there is «ويعرف حق كبيرنا» instead of «ويعرف شرف كبيرنا».
´Amr bin Shu'aib narrated that his father, from his grandfather, who said that the Messenger of Allah said:` 'He is not one of us who does not have mercy upon our young, nor knows the honor of our elders."
Hadith Referenceسنن ترمذي / كتاب البر والصلة عن رسول الله صلى الله عليه وسلم / 1920
Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever does not show mercy to our young ones and does not recognize the rights of our elders, has no connection with us."
Shaykh Muhammad Ibrahim bin Basheer
Benefit: In this hadith, compassion towards the young, respect for elders, and fulfilling their rights have been emphasized. By "kabir" (elder), a person who is greater in age or knowledge is meant. In some ahadith, scholars ('ulama) are also mentioned.
