What is the argument that can be presented to a friend who believes that charity and good deeds are sufficient substitutes for prayer?

The questioner should try to convince his friend, who has abandoned prayer, through encouragement, warning, and gentleness. He should remind him that prayer is the pillar of religion and the second pillar of Islam, and that whoever abandons it out of negligence is in great danger. He should also inform him that good deeds and charity do not suffice for the obligatory prayers, as prayer is the first thing a servant will be held accountable for on the Day of Resurrection. Therefore, he must fear Allah and perform his obligatory duties, for Allah has commanded the establishment and preservation of prayer, and the Prophet, peace be upon him, enjoined it even in the last moments of his life.
