46) Anyone who studies the creation of Allah will see some of the signs of His greatness. The Prophet (peace be upon him) said, describing the Kursiy (Footstool) and Throne: "The seven heavens, in comparison to the Footstool, are like a ring lying in the wilderness, and the superiority of the Throne to the Footstool is like the superiority of the wilderness to that ring." (Classed as saheeh by al-Albani)
47) This world should not be the main concern of the Muslim. Worry about his provision should not find any room in his heart or mind. Anas said: The Prophet (peace be upon him) said: "Whoever is mainly concerened about the Hereafter, Allah will make him feel independent of others and will make him focused and content, and his wordly affairs will fall into place. But whoever is concerned with this world, Allah will make him feel in constant need of others and will make him distracted and unfocused, and he will get nothing of this world except what is decreed for him." (Classed as saheeh by al-Albani.)
48) Prayer is the greatest pillar of Islam after the Shahadatayn, and it is not wavied for anyone so long as he is of sound mind. Whoever can pray standing must do that, otherwise he should pray sitting or on his side, or by making gestures, according to what he is able to do, and Allah does not burden any soul beyond its scope. That is because the Prophet (peace be upon him) said: "Pray standing, and if you cannot, then sitting, and if you cannot, then on your side." (Bukhari)
49) In prayer it is better to recite Qur'an from memory, because if a person recites from the Mushaf, he will be doing repeated actions such as holding the Mushaf, putting it down, and turning its pages. By doing so he will miss out on putting his right hand over his left hand on his chest when standing, or spreading out his arms during rukoo ans sujood. Some people carry the Mushaf to the imam's recitation in the prayer. This is something which should not be done.
50) If one is reciting Qur'an in situations other than in prayer, then reading from the Mushaf is better, because it is more accurate and helps one to remember better. But if reciting from memory is easier and helps one to concentrate more and have better presence of mind (khushoo'), then one should recite from memory.
