What is the ruling on gradually giving up smoking after repenting from it? Is the fact that committed friends do not ask about me evidence of their lack of brotherhood? And is showing them good deeds to prove repentance considered showing off (riya’)?

The questioner is congratulated on his repentance and advised to immediately strive to quit smoking, seeking Allah's help and firm resolve. He should also be diligent in performing prayers in the mosque, attending religious study circles, associating with righteous people, and observing voluntary fasts. This is in addition to remembering the dangers of smoking to health and its wastefulness of money. As for his relationship with committed friends, it should be nurtured through good deeds, spreading salutations, cheerfulness, and benevolence.
