"Indeed ,from them (the aahaad ahaadeeth) are those which require and action, so it is acted upon. So from Abu Hurairah who said: The Messenger of Allaah salla lāhu 'alayhi wa sallam said: "When any of you finishes the last tashahhud, he should seek refuge with Allaah from the four things: from the punishment of the Hellfire, from the punishment of the Grave, from the trials of life and death from the evil trials of the Dajjal" And from 'Aaishah: from the Prophet salla lāhu 'alayhi wa sallam, that he used to make supplication in the prayer: "O Allaah! I seek refuge in You from the punishment of the Grave, I seek refuge in You from the trials of the Maseehud-Dajjal, I seek refuge in You from the trials of life and death.O Allaah! I seek refuge in You from debt and sin" So these two ahaadeeth are 'Aahaad narrations and they contain the requirement of an action, ir to carry out this supplication after finishing the 'tashahhud'. So it is recommended to make this supplication after finishing 'tashahhud and it is permissible to make 'tasdeeq (attest) what is contained in them. However, "what is 'haraam (forbidden)' is to hold it with certainty-meaning to have it as part of ones 'aqeedah-as long as it only been reported in the aahaad hadeeth,adhannee (non- mutawaatir) proof.However ,if it occurs in 'mutawaatir form,then it is obligatory to make it part of one 'aqeedah"(Ad-Dawsiyyah (p.6) of Taqeedu-Deen an-Nabahaanee-the founder of Hizbut-Tahrir -may Allaah forgive him )
Making 'tasdeeq' of the Punishment in the Grave, whilst forbidding a person to have 'aqeedah'(belief) in it,is a contradiction in terms. Since-as has preceded in the words of al-Haafidh Ibn Hajr-'tasdeeq' is attesting the truth of something in the heart, which is the same as 'aqeedah' and which thereby necessitates 'eemaan'. However, differentiating between 'tasdeeq' and 'aqeedah' is innovated speech; opposing the way of our Salaf. Unfortunately,the likes of this innovation has been clearly stated by the present leader of 'Hizbut-Tahrir in Britain, when he said: "We trust it; and I encourage all of you 'an tasaddiqoo bi 'adhaabil-Qabr(to have 'tasdeeq in the Punishment of the Grave). I encourage all of you 'antasaddiqoo bi awdatil-Mahdee (to have 'tasdeeq' in the coming of the Mahdee). I encourage you for that. "But whoever believes in that, he is sinful" (From an available taped lecture entitled: 'Punishment of the Grave (Regents Park Mosque,2nd May 1992 CE] by Omar Bakri Muhammad.)
