How can one overcome weakness of faith and spiritual apathy in worship, such as delaying prayer and少 (qillat) reading the Quran, despite possessing knowledge of God's rights?

We advise you to repent to Allah and start a new chapter in your relationship with Him, by striving in supplication for Allah to renew faith in your heart, by struggling against your lower self to remain steadfast in obedience, by preserving the prayer at its appointed times, by making a daily portion of Qur’an recitation, by frequently remembering Allah, and by avoiding sins. Reflect upon the names and attributes of Allah, upon death and the terrors that follow it, and upon Paradise and Hell, and accompany righteous women who remind you of obedience to Allah.
