and attributes are true and must be affirmed in the way befitting Allah (Exalted be He) along with absolute belief that He is not similar to His creatures in any of His Attributes or His Essence. This is based on the view of AhlulSunnah walJama`ah (those adhering to the Sunnah and the Muslim main body) among the Prophet's Sahabah and their followers.
All the prophets unanimously had faith in all that and all the messages were revealed with those teachings, the most complete of them all is the Holy Qur'an. You have to believe in and adhere to it which is the certain truth. One must also believe in Prophet Muhammad (peace be upon him), and all prophets as well and in what they narrated about the angels, the books, the Paradise, and Hell, the Day of Resurrection, the judgment and reward, the torment or bliss in the grave, and the belief in Predestination whether good or bad.
All Mukallafs, women and men, slaves and free persons, Arabs and nonArabs, poor and rich, rulers and subjects, Jinn and mankind, must believe in what Allah (Exalted be He) and His Messenger (peace be upon him ) told us. It is obligatory upon them to believe in what Allah and His Messenger said about the past messengers from Adam and other messengers who came after him. They must believe in the guidance those messengers brought and believe that Allah (Exalted be He) has sent them down to call people to goodness, guidance, and Tawhid and that they conveyed the message and fulfilled the trust. Moreover, they must believe in all the reports of the People of Nuh, 'Ad and Thamud and the other people about whom Allah told their account.
Every slave must believe in all what Allah (Exalted be He) and His Messenger (peace be upon him) said in the Qur'an and Sunnah. He has to believe in the punishment and blessings in the grave as the grave is a garden of the gardens of Paradise for the believer or a pit of the pits of Hell for the disbeliever.
The sinful person is liable to the danger of punishment in his grave except whom Allah (Exalted be He) has given mercy.It is authentically reported in the Two Sahih (authentic) Books of Hadith (i.e. AlBukhari and Muslim)that the Prophet (peace be upon him) once passed by two graves and said: Those two persons (in the graves) are being tortured and they are being tortured not for a great thing (to avoid). One of them used to go about with calumnies, and the other never saved himself from being soiled with his urine. The phrase never saved himself from being soiled with his urine means he did not take precautions to avoid contaminating himself or his clothes. Another narration reads, They were tortured in their graves for committing these two sins. This is a rapid torture.
The Hadith points out that committing sins is dangerous. Every believer, therefore, has to hold fast to the religion of Allah through words, actions, and beliefs and adhere to the obligations and avoid the prohibitions. He must believe in what Allah (Exalted be He) and His Messenger (peace be upon him) said about the states of the dead in their graves, as the grave is a garden of the gardens of Paradise, or one of the pits of Hell. Once the deceased is placed inside his grave, two angels ask him about his Lord, religion, and Prophet. For the believers, Allah (Exalted be He) would send down tranquility into their hearts and add faith to their faith. When asked in his grave, the believer would answer my Lord is Allah, Islam is my religion, and Muhammad (peace be upon him) is my Prophet. As the Muslim was holding fast to his faith and to his religion during his lifetime, for this reason Allah (Exalted be He) would grant him peace of mind and tranquility in his grave.
However, the disbeliever or the hypocrite, when asked in the grave they would find no answer to give and would say instead "I only followed what the astray people were saying." On giving that answer, the disbeliever would be hit by a sledgehammer, and a scream would come from him to be heard by all creatures except man, who would have been frightened if could hear that. As such, people would be resurrected and judged on the Day of Resurrection. When the trumpet sounds on the Last Day, all people will die and be resurrected and judged in accordance with their deeds. The Qur'an and Sunnah asserted that Israfeel will blow the Trumpet. At the first blowing, all people die and are resurrected after the second blowing. Then, they will rise from graves wherever they may be in the sea or whatever, to be gathered and judged in accordance with their deeds. All this must be believed in. One must prepare for that Last Day by the belief in the Oneness of Allah and following His ordinances and avoiding His disobedience. Afterwards, the balances will then be erected and the deeds will be weighed. The happy ones are those who are judged and given their records in their right hands, and the wretched are those people who are judged and given their records in their left hands. We ask Allah for safety.
It is necessary to remember that great day and horrible situation in order to prepare for it. It is the Great day of Resurrection; the day of calamities and distresses whose length is fifty thousand years.
The angels and the Rûh [Jibrîl (Gabriel)] ascend to Him in a Day the measure whereof is fifty thousand years. So be patient (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ), with a good patience. Verily, they see it (the torment) afar off. But We see it (quite) near.
Every Muslim has to believe in and prepare himself for that day. They must obey Allah, follow His Laws and avoid His prohibitions, advise one another in righteousness and stay firm with truth. They must enjoin the right and forbid the wrong and guide the ignorant and the other righteous activities.
