Mukhtasar Bukhari

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) informed about the death of Najashi on the day he passed away. So the Prophet (peace be upon him) went to the place of prayer, arranged the people in rows, and said four takbirs, that is, he offered the funeral prayer in absentia.
