Allah -azwj Says...
Allah -azwj Says: There is a witness to him, who comes immediately behind him (my Prophet) [101] This is the ‘Hujjat Allah’ [102] who was supposed to continue in executing Divine Commands (after Prophet -saww ) and people recognised him that he is the only deserving person to take the place of Prophet -saww after his demise, and that no one is capable of executing the Divine authority after the Holy Prophet -saww except the one who is ‘Tahir’ (pure) like the Prophet -saww himself.
And as for the transfer of Prophet’s status to him, his successor -asws should never ever been found to indulge in Kufr, and without leaving it even for a short time, so that no negative aspects about him -asws are raised as he -asws could never be found supporting kufr and would never ever have played any role in the commitment of sins.
This is due to the fact that Allah -azwj has made others susceptible to be easily influenced by the Kufr powers, frequently and again and again, even after embracing Eman, therefore, Allah -azwj has never given this role to anyone else but to His selected Prophets -as and Divine successors -as . As Allah -azwj has told Ibrahim -as : I will never give this position to those who have committed sins’ . [103] Do you know, why does Allah -azwj recognise the ‘Shirk’ as cruelty?
‘Indeed, ‘Shirk’ is committing a great cruelty’ . Thus, Ibrahim -as was informed that the Divine position, which Allah -azwj refers to ‘Imamat’ can never be granted to those who have worshiped the idols. Ibrahim -as then prayed: O my Lord, save me and my progeny from worshiping idols .
[104] Be informed, the actions of monafiqeen against the Sadiqeen -asws , and the Kufr against Wali-Allah -asws are considered to be serious violations and great sins and this is the reason why Allah -azwj has clearly distinguished in His -azwj book, the just and the unjust, the pure and the impure and the momin and the kafir.
Therefore, the successor of a Prophet -as , after his demise, can never be anyone else but the ‘one’ who is the most truthful, the most just, and the most pure and the most eloquent. The Divine ‘Amanat’ (Trust) which Allah -azwj has mentioned in the Book (entrusting Divine Position), this ‘Amanat’ is not permissible and appropriate for anyone else to posses but for the Prophets -as and their successors -as .
As Allah -azwj has made them -asws custodian of His -azwj Commands for the masses and has established His ‘Hujjat’ (Proofs) on the earth through them -asws .
