As after the death of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam, it was destined that Abubakr Radiyallahu ‘Anhu would take his place, therefore such masaa-il were a speciality only known by Sayyidina Abubakr Radiyallahu ‘Anhu. A few ahaadith are mentioned as an example:No nabi’s death occurs till that nabi becomes a muqtadi, (performs prayers behind) in salaah of among his ummah.The ahaadith on the collecting of zakaah and its nisaab rate.The portion between my grave and mimbar is a part from the gardens of jannah (paradise). 4. The ambiyaa do not have any heirs (No one inherits from a nabi).When Allah Ta’aala gives a nabi any rizq (sustenance), that person is responsible for its administration, who is the khalifah of the nabi.The one that becomes a khalifah or a king, and he carelessly chooses a deputy, the curse of Allah befalls him. By carelessness it is meant that he does not consider the facts.The hadith on the punishment for adultery.The hadith on consultations at the time of jihaad.The basis of the deen is on Laa ilaaha iliallaah.The khilaafah be among the Quraysh.The virtues of the Ansaar and the advice to the khalifahs on caring for them.The punishment of theft.A just and humble king is the Shadow of Allah on earth.The one who wishes to be safe from the hardships of jahannam and remain under the shadow of Allah, should not be harsh towards the Muslims, but treat them with love and care.The nations that discards jihaad, general calamities and hardships befall them. (Tarikhul Khulafaa).
