Is a person considered a traitor for withdrawing from the Muslim Brotherhood after his morals became corrupt, then repenting? And is his repentance accepted? And can he memorize the Qur'an at the age of 35?

We congratulate the questioner on his repentance, and advise him to be diligent in the means of steadfastness and beware of deviation, while pointing to the vastness of Allah's mercy and forgiveness. We inform him that withdrawing from the Muslim Brotherhood group is not treason, but it is recommended to associate with the righteous and not to distance oneself from them due to the shortcomings of some. We affirm that the questioner's age is still suitable for memorizing the Qur'an.
