The grave is a garden from the gardens of Paradise, or a pit from the pits of the Fire

This listener, the brother (M. J. M), asks about the deceased—about the Reckoning of the deceased. He says: Is the Reckoning immediate, where he enters Paradise or Hellfire? Or is it delayed until the Day of Resurrection for the Reckoning? Please inform us, may Allah guide you?
Answer: The texts from the Prophet (peace and blessings be upon him) indicate that the grave is either a garden from the gardens of Paradise or a pit from the pits of Hellfire. When a servant is taken, he is given glad tidings at his grave of Paradise if he was a believer, and given tidings of Hellfire if he was a disbeliever. If he enters his grave and is asked about what is obligatory but does not respond, he is tormented in his grave. This torment is the beginning of the torment in the Hereafter. Similarly, when a believer enters his grave, he is granted bliss in his grave, and a door to Paradise is opened for him, from which he receives its bliss and sweetness. He sees his place in it, and he sees his place in Hellfire, and that Allah has protected him from it and spared him from it. The disbeliever likewise sees his place in Paradise and that a barrier has been placed between him and it because of his disbelief, and he sees his place in Hellfire, from which he receives its heat, torment, and punishment. His grave becomes a pit from the pits of Hellfire, in which he is tormented according to his evil deeds and his disbelief in Allah (Mighty and Majestic).
So the grave is a beginning of the beginnings of bliss for the believer, and a beginning of the beginnings of torment for the disbeliever. The sinner is in danger; the sinner who died upon sins may be tormented in his grave, even if he is not a disbeliever. However, it is established from the Messenger of Allah (peace and blessings be upon him) that he looked upon two graves being tormented. As for one of them, he used to spread talebearing, and as for the other, he did not protect himself from urine—meaning he did not purify himself from urine. He was informed that they were tormented because of this sin. In another hadith: “Most of the torment of the grave is from urine.” “Protect yourselves from urine, for most of the torment of the grave is from it.” This indicates that sins may cause their perpetrators to be tormented in the grave because of them. By this, you know that the grave is either a place of torment or a place of bliss, but it is a preliminary torment and a model of the torment of Hellfire, and a preliminary bliss and a model of the bliss of Paradise.
Therefore, the believer should be cautious and prepare for the Hereafter, and should make ready for meeting Allah. He should be cautious of the causes of torment, and that is by striving in the obedience of Allah, standing firm upon the command of Allah, staying away from the sins of Allah, and advising one another to truth and patience upon it, until you meet your Lord and you are in this state. You meet your Lord and you are striving in the obedience of Allah, staying away from the prohibitions of Allah, and standing by the limits of Allah. You help your brothers in good and advise them to truth and patience upon it.
This is how the believer is until he meets his Lord (Mighty and Majestic). He is patient and enduring, staying away from everything Allah has forbidden and hastening to what pleases Allah, until he meets his Lord (Mighty and Majestic). By this, he will be in his grave in bliss and great good, and in a continuous garden from the gardens of Paradise until he meets his Lord (Mighty and Majestic), and he will obtain what is greater and more magnificent than the bliss of Paradise. And the opposite is the opposite: the disbeliever is the contrary of that. When he dies, he is in torment and punishment, and what comes after it is worse than it. We ask Allah for safety. Yes.
