A Muslim has no way of knowing whether he or she will be accepted by Allah until the day of judgment. Muhammad himself said he did not know what would happen to him on the day of judgment.

An acknowledged Hadith tells about Muhammad going to visit a house where the body of a Muslim who had died still lay. A woman addressed the dead body, saying:

“May Allah have mercy on you. I testify that Allah has honoured you. Muhammad asked the woman, “How do you know that Allah has honoured this man? “I know, by Allah,” she said. Muhammad replied, “This man, death struck him and I wish him the best in the name of Allah. By Allah, although I am the Messenger of Allah, I know not what will happen to me, just like you.”
(The Authentic of Bukhari, vol.9, book 87, no. 145. Narrated by Kharija bin Zaid bin Thabit).

The faithful disciple of Mohammad, Abu Bakr, also confessed that he feared the judgment of Allah. He said, “If one of my feet was in heaven, and the other outside, I would still would not trust the ingenuity of Allah.”

What Abu Bakr meant was that his eternal future was mysterious until both his two feet were in Paradise. Abu Bakr was nicknamed “the weeping” because he was continually crying while praying. When asked why, he replied:

“Every time I begin to pray, I imagine Allah standing before me and the king of death behind me, paradise on my right and hell on my left, and I do not know what my God will do to me . “

It should be noted that five times a day in their prayers all Muslims pray, “Peace and salvation be upon Muhammad.” They pray that God will grant the entrance to heaven. A man can only give what he has. If the leader of Islam himself does not know where he is going, what about his disciples?

According to Ibn Mas’ud, the Prophet said: “The people most worthy of my intercession on the Day of Resurrection will be the ones who have prayed most for me.” (Narrated by At-Tirmidhi)

On the other hand, Christians do not need to pray, “Peace and salvation be upon Him,” about Jesus. Why? Because He is the Lord of all. He is the Prince of Peace (Isaiah 9: 6), the giver of peace (John 14:27, Colossians 1:20), “For in him dwells all the fullness of the Godhead bodily” (Colossians 2: 9) .

Christ is our “peace” (Ephesians 2:14) and He gives us true spiritual peace. The Christian knows that to be absent from the body is to be present with the Lord. How?

You can read John chapter 5 here, but this is a saying of Jesus:

“Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life.” John 5:24

As He was dying on the Cross, Jesus had no doubt where He was going, and a thief next to Him turned in repentance and faith to trust Him. The Lord Jesus Christ said these words to that thief:

“Truly, truly I say to you, today you shall be with me in Paradise.”

Jesus had no doubt whatever where He would go the moment He died, and He reassured the dying thief that they would meet there that very day.
