How can we improve as Muslims other than always doing our sala't and memorizing Qur'an? Can you give the do's and don'ts of being a Muslim?

In order to improve one's life as a Muslim, we advise the following: i) Associate with pious people (if possible with Allah-Fearing Ulama) and abstain from people who have no respect for the laws of Allah. ii) Obtain reliable Islamic literature under the supervision of reliable Ulama and make a firm intention to practise whatever one learns. iii) Abstain from committing sin.
iv) If you experience any difficulty in carrying out the above, search for a spiritual guide and follow his guidance to the best of your ability. The spiritual guide must be an Allah-Fearing person strictly adhering to Shari' ah and Sunnah.

And Allah Ta'ala Knows Best
