It's well nown in islam that God keeps the Believers Firm in This Life and in the Hereafter with a Word that stands Firm.
Al-Bukhari recorded that Al-Bara bin `Azib, may Allah be pleased with him, said that the Messenger of Allah said,
(When the Muslim is questioned in the grave, he will testify that, `La ilaha illallah', and that Muhammad is Allah's Messenger, hence Allah's
statement, (Allah will keep firm those who believe, with word that stands firm in this world, and in the Hereafter.) Muslim and the rest of the Group
recorded it. Imam Ahmad recorded that Al-Bara bin `Azib said, "We went with the Messenger of Allah to attend a funeral procession of an Ansari man.
We reached the grave site when it had not yet been completed. The Messenger of Allah sat, and we sat all around him, as if there were birds hovering
above our heads. The Prophet was holding a piece of wood in his hand, poking the ground with it. He next raised his head and said twice or thrice,
(Seek refuge with Allah from the punishment of the grave.) He said next,
(When a believing slave is reaching the end of his term in the life of this world and the beginning of his term in the Hereafter, a group of angels,
whose faces are white and as radiant as the sun, will descend onto him from heaven. They will carry with them white shroud from Paradise, and
fragrance for enshrouding from Paradise. They will sit as far from him as the sight goes. Then, the angel of death, will come until he sits right next
to his head, saying, "O, good and pure soul! Depart (your body) to Allah's forgiveness and pleasure.'' So the soul flows (out of its body), just
as the drop flows out from the tip of the jug, and the angel of death captures it. When he captures the soul, they (the group of angels) will not
leave it with him for more than an instance, and they will seize it and wrap it in that shroud, and in that fragrance. A most pleasant musk scent ever
found on the earth, will flow out of the soul, and the angels will ascend it (to heaven). They will not pass by, but they will say, "Whose is this
Tayyib (good) soul'' They (the angels who are ascending the soul) will reply, "Such person, the son of such and such person,'' -- calling him by
the best names that he used to be called in the world. They will reach the lower heaven and will ask that its door be opened for him, and it will be
opened for them. The best residents of every heaven will then see him to the next heaven, until he is brought to the seventh heaven. Allah, the
Exalted and Ever High, will say, "List my servants record in `Illiyyin and send him back to earth, for I have created them from it, and into it I
shall return them, and from it I shall bring them out once again.'' The soul will be joined with its body, and two angels will come to him, sit him
up and ask him,
"Who is your Lord''
He will say, "Allah is my Lord.''
They will ask him, "What is your religion''
He will say, "My religion is Islam.''
They will say to him, "What do you say about this man (Prophet Muhammad) who was sent to you''
He will say, "He is the Messenger of Allah.''
They will ask him, "And what proof do you have about it'' He will say,
"I read the Book of Allah (the Qur'an), and had faith and belief in him.''
Then, a caller (Allah) will herald from heaven, "My servant has said the truth. Therefore, furnish him from Paradise, and let him wear from (the
clothes of) Paradise, and open a door for him to Paradise.'' So he is given from Paradise's tranquillity and good scent, and his grave will be
expanded for him as far as his sight can reach. Then, a man, with a handsome face and handsome clothes and whose scent is pleasant, will come to him,
saying, "Receive the glad tidings with that which pleases you. This is the Day which you were promised.'' He will ask him,
"Who are you; for yours is the face that carries the good news''
He will reply, "I am your good works.''
He will say, "O Lord! Hurry up with the commencement of the Hour, hurry up with the commencement of the Hour, so I can return to my family and my
