All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
This type of question does not lead to doing good deeds, so you should not preoccupy yourself with it, and there is no need to worry.
The fact that you often get such questions in your mind may be because of the whispers of the devil to distract you from what is beneficial to you in regard to the matters of your religion and your worldly life.
So you should be mindful of this and make every effort to repel the whispers of the devil.
With regard to this issue, we did not come across any evidence or any explicit statements of the scholars on it. What is confirmed is that the Prophet will be the first person to enter Paradise and that his nation (the Muslims) will be the first nation to enter it. However, the fact that his nation is the first nation to enter Paradise does not necessitate that they enter before the Prophets.
What is understood from the statements of some scholars is that the Prophets precede this nation in entering Paradise.
For instance, Ibn Al-Qayyim said in Haady Al-Arwaah, “Paradise is forbidden to the Prophets until Muhammad enters it, and it is forbidden to the nations until his nation enters it.”
On the other hand, there is an explicit hadeeth that was reported about the Prophets preceding the people in entering Paradise. Were this hadeeth authentic, it would have put an end to any dispute or confusion, but it is at least weak. This hadeeth was reported by Ad-Daylami in Musnad Al-Firdaws from Jaabir ibn ‘Abdullah, may Allah be pleased with him; its wording is as follows, “The first to enter Paradise are the Prophets.” Muhammad ibn Taahir Al-Maqdisi classified it as weak in his book Thakheerat-ul-Huffaath.
Allah knows best.
