and His angels, His Books, His messengers, the Last Day, and the divine decree, both its good and its evil. This is faith, as the Prophet—may Allah bless him and his family and grant them peace—explained when Gabriel asked him about faith. He replied: “It is to believe in Allah, His angels, His Books, His messengers, the Last Day, and the divine decree, both its good and its evil.” (1)
As for His words, ﴿and perform righteous deeds﴾, this means that they perform righteous deeds. Righteous deeds are those founded upon sincerity to Allah and adherence to Allah’s revealed law. Thus, whoever performs a deed in which he associates someone else with Allah will have that deed rejected. The Prophet—may Allah bless him and grant him peace—related that his Lord, Almighty, said: “I am the One most free of any need for partners. Whoever performs a deed in which he associates another with Me, I reject him and his act of association.” (2)
As for following the Messenger of Allah—may Allah bless him and his family and grant them peace—any deed that is not in accordance with Allah’s revealed law is invalid and rejected, for the Prophet—may Allah bless him and his family and grant them peace—said: “Whoever performs a deed that is not in accordance with our way will have it rejected.” (3)
Accordingly, the worship of one who shows off—worshipping Allah while making a display before people, meaning that he displays his worship so that they will see and praise him—is rejected as well. He does not seek to draw closer to people; he seeks to draw closer to Allah, but wants people to praise him for drawing closer to Allah and worshipping Him. Such a person is showing off, and his deed is rejected. Likewise, if someone recites words from the Quran or words of remembrance and raises his voice so that people will hear him and praise him for remembering Allah, he too is showing off, and his deed is rejected because he has associated someone else with Allah in it: he wanted people to praise him for worshipping Allah. As for one who directs worship to people, he commits major shirk. This means someone who stands in prayer before another person out of veneration for him rather than for Allah, and bows and prostrates to that person
