As-Salaam alaikum,
Abdur-Rahman Ibn Sakhr ad-Dowsi, known also as Abu Hurairah (father of a kitten), may Allah be pleased with him, is one of the illustrious companions of Prophet Muhammad, Sallallahu alaihi Wasallam. His name is synonymous with Prophetic tradition (hadith) in Islam, and like all the companions, he was/is known to have been extremely trustworthy, just and reliable. He was an outstanding individual and his life speaks of sacrifice, devotion and love for the Messenger of Allah and for the religion of Islam.

Abu Hurairah narrated more than 5,000 Prophetic ahadith/narrations that today stand as beacons of guidance to Muslims and the human race. When most companions of the Prophet, alaihi-salaat was-salaam, from the Muhajirun and Ansar were either busy with their cattle and sheep or in the market places, Abu Hurairah used to be in the company of the Prophet. He was present when the other companions were absent and revising what he learnt/heard from the Prophet, when they may have forgotten. Partly, this accounts for his many narrations of ahadith.

From his worship, spirituality and character, are the following which we stand to learn from and adopt:--

(1) Abu Hurairah had the habit of fasting every Monday and Thursday.

(2) He used to recite 12,000 TASBIHI [Subhanallah] daily.

(3) His daily habit-- Maymun Ibn Maisurah narrates that Abu Hurairah, may Allah be pleased with him, had the habit of calling out loud every morning: 'The night has gone and the day has come, and the family of Pharaoh have been presented to the Fire'! (based on the Qur'anic ayat 40:46). He would do so in the evening as well and no one would hear him except that they would seek protection from the fire.

(4) Abu Usman an-Nahdi reports: 'I hosted Abu Hurairah and his family for 7 days. It was him, his wife and a servant. They used to divide the night amongst themselves in prayer-- taking turns between sleeping and praying.
