Hazrat kaab ahbar relates that I read in the verses that were sent on hazrat Musa علیہ السلام that: oh Musa! For the Two rakat that hazrat Ahmed ﷺ­ and his nation will offer at the time of fajjar prayer, I will forgive all their sins of the whole day and night and will bring them under My protection. Oh Musa! In the four rakat that hazrat Ahmed ﷺ­ and his nation will offer at the time of zuhar prayer, the first rakat will bring them forgiveness, second will make their good deeds heavier in the balance, the third will cause the appointment of angels around them that are constantly engaged in offering istighfar for their sake and the fourth would allow the door of the skies to be opened so that beautiful hoorain can view them. Oh Musa! In the four rakat that hazrat Ahmed ﷺ­ and his nation will offer at the time of ASR, all of the angels of the earth and sky would beg forgiveness for that person and if the angels beg forgiveness for someone than I do not punish that person. Oh Musa! For the three rakat of magrib that hazrat Ahmed ﷺ­ and his nation will offer, I will open the doors of the sky for them and will provide all that they ask for. Oh Musa! the four rakat of isha that hazrat Ahmed ﷺ­ and his nation will offer will hold weightage more than all that is in this world and the universe and his sins will be forgiven to the extent that they will be like new born babies. Oh Musa! When hazrat Muhammad ﷺ­ and his nation will perform ablution according to my teachings then they will be rewarded jannah that has dimensions equal to the earth and shy.  Oh Musa! When hazrat Muhammad ﷺ­ and his nation will offer the fasts of Ramadan then for every fast they will be rewarded a city in paradise and for every nafal good deed the reward will be equal to a farz and also in the month of Ramadan I have created LAILA-TUL-QDAR in which whoever begs for forgiveness with true humbleness and sincerity would be rewarded the status of 30 martyrs if he dies that night or during the month of Ramadan.Oh Musa! Amongst hazrat Muhammad ﷺ­‘s nation there will be those too who would repeat that there is “no god but Allah and hazrat Muhammad ﷺ­ is the messenger of Allah” and the reward for this would be equal to that of any messenger of Allah and My blessings would be guaranteed on them and also they would be protected from My wrath and while they keep repeating this shahadah the doors of forgiveness would not be closed on them.

The shahadat of the nation of Hazrat Muhammad ﷺ­ on the Day of Resurrection

Hazrat Abu Huraira    رضی اللہ عنہا relates Prophet Muhammad ﷺ­ ‘s saying that on the day of judgement the nation of Hazrat Nuh علیہ السلام would be called first. Hazrat Nuh علیہ السلام would be questioned that did you propagate the call of Islam to which he would answer that yes Allah I did. The nation of Hazrat Nuh علیہ السلام would then be asked that did Nuh علیہ السلام call you towards the religion of Islam. They would answer that he did not and if some messenger had come to us with the call towards You (Allah) we would certainly have been obedient and honest. And Nuh علیہ السلام did not to come to us with the call to Islam. Hazrat Nuh علیہ السلام would then be asked is there any witness to your call to Islam? The answer would be yes and when the identity of this witness would be inquired then Hazrat Nuh علیہ السلام would request that the nation of Prophet Muhammad ﷺ­ be called to testify. This nation would testify that Hazrat Nuh علیہ السلام did indeed propagate the call to Islam.  The nation of Hazrat Nuh علیہ السلام would then question the nation of Hazrat Muhammad ﷺ­that since we are the first community and you are the last then how can you testify in our matter. The nation of Hazrat Muhammad ﷺ­would say that we bear witness to the fact that Allah sent a Messenger to us bearing His (Allah) word (Quran) in which the event of  your nation is described.

Hazrat Abu Huraira رضی اللہ عنہا says that we are the last nation but on the Day of Judgement we would be the first and the following saying of Allah reinstates this fact in such words:

Sahih International

That was a nation which has passed on. It will have [the consequence of] what it earned and you will have what you have earned. And you will not be asked about what they used to do. (134-Al-Baqarah)
