We are obligated to have Faith in everything that the Prophet (sallAllaahu ‘alayhi wa sallam) informed us about and in what has been authentically attributed to him through reports, whether we witnessed it or it was hidden from us. We know that it is a reality and the truth. This is the same with regard to whether we comprehend it or we do not comprehend it.
We do not go beyond the outer actuality (i.e. literalness) of its meaning, such as the hadeeth concerning the Israa and the Mi’raaj. It occurred while the Prophet was awake and not in a dream, for indeed the Quraish denied it and considered it something incredible. And they did not used to deny dreams.
Another example of that, is when the angel of death approached Moosaa in order to take his soul. He (Moosaa) struck him and gouged his eye, so he returned to his Lord who gave him his eye back.
Another example of that: are the signs of the Hour, such as the emergence of the Dajjaal, the descent of ‘Eesaa bin Maryam, who will then kill him, the coming out of Ya’jooj and Ma’jooj, the emergence of the Beast, the rising of the sun from the west, and all that is related to this from what has been authentically reported. 
The punishment and pleasure of the grave are true. The Prophet (sallAllaahu ‘alayhi wa sallam) would seek refuge from it (the punishment) and he commanded that it be done in every prayer.
The trial of the grave is true. The questioning of Munkar and Nakeer is true. The resurrection after death is true, and that will occur when Israafeel blows on the trumpet.
“And behold from the graves they will come out quickly to their Lord.” [Surah YaaSeen (36): 51]
Mankind will be gathered on the Day of Judgement, barefoot, naked, uncircumcised, and having nothing with them (i.e. possessions). They will stop at the final place of standing, until our Prophet (sallAllaahu ‘alayhi wa sallam) intercedes for them and
Allaah, Blessed and Exalted, reckons with them (i.e. judges them). The Balances will be set up, the records will be distributed and the pages containing the deeds of each individual will be dispersed into the right hands and the left hands.
“Then as for him who will be given his record in his right hand, he surely, will receive an easy reckoning. And will return back to his family in joy! But whoever is given his record behind his back (or in his left hand), he will invoke (for his) destruction. And he shall enter a blazing Fire and made to taste it’s burning flames.” [Surah Al-Inshiqaaq (84): 7-12]
The Balance (Al-Meezaan) has two scales and a tongue, with which it will weigh the deeds.
“Then those whose Balances (of good deeds) are heavy, they are the successful. And those whose Balances (of good deeds) are light, they are those who lose their own selves, in Hell will they abide.” [Surah Al-Mu’minoon (23): 102103]
Our Prophet Muhammad (sallAllaahu ‘alayhi wa sallam) will have the Fountain (AlHawd) on the Day of Judgement. Its water is whiter than milk and sweeter than honey. Its drinking vessels are as numerous as the stars in the sky. Whosoever drinks a serving from it, will never thirst again after that.
The Bridge is true. The righteous ones will cross it and the evil ones will fall from it.
Our Prophet (sallAllaahu ‘alayhi wa sallam) will intercede for the members of his ummah who have entered the Hellfire due to their major sins. Thus they will be extracted from it due to his (sallAllaahu ‘alayhi wa sallam) interceding (for them), but only after having been set ablaze and burned to ashes and charcoal. Then they will enter Paradise due to his intercession.
There will also be interceding done by the rest of the prophets, believers and angels. Allaah says:
“And they cannot intercede except for him with whom He is pleased. And they stand in awe for fear of Him.” [Surah Al-Anbiyaa (21): 28]
The intercession of the interceders will be of no avail to the disbelievers. Paradise and the Hellfire are two creations that will not cease to exist. Paradise is the abode of the close friends of Allaah, while the Hellfire is the place of punishment for His enemies. The inhabitants of Paradise will abide therein (i.e. Paradise) forever.
“Verily, the sinful evildoers will be in the torment of Hell to abide therein forever. (Their torment) will not be lightened for them, and they will be plunged into destruction with deep regrets and sorrows.” [Surah Az-Zukhruf (43): 74-75]
Death will be brought in the form of a sturdy ram and slaughtered between Paradise and Hellfire. Then it will be said: “O inhabitants of Paradise! Eternity for you and no (more) death! And O inhabitants of Hellfire! Eternity for you and no (more) death!”
