He has recently started to pray regularly

Praise be to Allah.

Congratulations on your repentance, congratulations on your repentance. 

Allaah rejoices greatly over the repentance of His believing slave. 

Al-Bukhaari (6309) and Muslim (2747) narrated that Anas ibn Maalik (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Allaah rejoices more over the repentance of His slave when he repents than any one of you would rejoice over his camel that ran away from him in the wilderness, carrying his food and drink, and he despaired of it so he came to a tree and lay down in its shade, having given up on his camel. Then while he is like that, suddenly he sees it standing in front of him, so he takes hold of its reins and says, because he is so happy, ‘O Allaah, You are my slave and I am Your lord!’ – making this mistake because he is so happy.” 

We ask Allaah to make us and you steadfast in adhering to Islam until death. 

You should also do a lot of good deeds, especially during this blessed month. 

Adhere to fasting and praying Taraaweeh, and reading Qur’aan. And give a lot of charity, because charity is one of the means of forgiveness of sins. 

With regard to acquiring knowledge, you could set aside time for yourself each day to read some useful booklets and listen to lessons via the internet or on tapes.

You could also read some of the answers on this site, especially those that have to do with the rulings that every Muslim needs to know, such as the rulings on tahaarah (purity), wudoo’, ghusl, prayer, etc. 

If you find any matter difficult to understand, we would be happy to hear any questions you may have. 

May Allaah help you to do that which He loves and which pleases Him. 

And Allaah knows best.
