It is narrated from Sayyiduna Abdullah bin Zayd bin Abd Rabbih (may Allah be pleased with him) (he is the one who was shown the words of the call to prayer (adhan) in a dream) that he gave some wealth in charity to his parents, then they both died, so the Messenger of Allah (peace and blessings be upon him) returned that wealth to him as inheritance. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), provided that Abu Bakr bin Amr bin Hazm heard it from Abdullah bin Zayd, and the two Shaykhs did not record it.
