Relying on the authority of Ibn Mas`ud al-Ansari, al-Dar Qutni indicates the following in his Musnad: The Messenger of Allah has said: "Whoever prays without blessing me and my , his prayers will never be accepted."[^137] In his book Al-Sawa`iq al-Muhriqa, Ibn Hajar says, "Al-Daylami has quoted the Prophet saying that everyone's supplication is withheld till he invokes Allah's blessings unto Muhammad and the Progeny of Muhammad."[^138] Likewise, al-Tabrani in his Al-Awsat has quoted Ali, peace be upon him, saying that everyone's supplication is withheld till he invokes divine blessings unto Muhammad and his Progeny.[^139] Thus do we come to know how the Sahih books of "Ahl al-Sunnah wal Jama`a" describe the correct way of invoking Allah's blessings unto Muhammad and his Progeny, that Allah does not accept the prayers of anyone unless he blesses Muhammad and and his Progeny, and that the supplication of every Muslim is withheld till he invokes Allah's blessings unto Muhammad and his Progeny.
It is, by my life, a great virtue and a sublime feat whereby are favored over all other humans; through them does a Muslim seek nearness to his Lord. But "Ahl al-Sunnah wal Jama`a" were angered by leaving this feat of alone. They realized the dire consequences of doing so.
No matter how many false "merits" and alleged "feats" can one attribute to Abu Bakr, Umar, Uthman, and all the sahaba, such "merits" and "feats" can never reach the lofty status of , nor can they reach its zenith simply because the prayers of all those who thus attribute and allege can never be accepted by Allah so long as they do not seek nearness to Him by invoking His blessings unto Ali ibn Abu Talib next to Muhammad, since he is the master of the `Itrat, as everyone knows.
It is for this reason that they resorted to its adulteration by adding something from their own selves which the Messenger of Allah never mandated in the hope of enhancing the status of their masters among the sahaba, deliberately curtailing this invocation from the very first century.
Notice how whenever they wrote a book, they left it without stating the complete blessing unto Muhammad and his Progeny, and whenever they mention "Muhammad", or "the Prophet", or "the Messenger of Allah", they say: Salla Allahu alaihi was sallam (Allah blessed and saluted him), removing any reference to the Progeny of Muhammad.
