Malik said, "No-one should carry the Quran by its strap, or on a cushion, unless he is pure. If it were permissible to do so, it would also have been permissible to carry it in its cover. This is not because there is something on the hands of the one who carries it by which the Quran will be soiled, but because it is disapproved of for someone to carry the Quran without being pure out of respect for the Quran, and in order to honour it."
Malik said, "The best thing that I have heard about this is the ayat 'None touch it except the purified.' (Sura 56 ayat 79) It ranks with the ayat in Surat Abasa (Sura 80), where Allah, the Blessed and Exalted, says, 'No, it is a reminder, and whoever wishes will remember it. Upon honoured pages, exalted and purified, by the hands of scribes, noble and obedient.' "
Muwatta Malik Book 15, Hadith 2
While I was praying with the Messenger of Allah (ﷺ), a man in the company sneezed. I said: Allah have mercy on you! The people stared at me with disapproving looks, so I said: Woe be upon me, why is it that you stare at me? They began to strike their hands on their thighs, and when I saw them urging me to observe silence (I became angry) but I said nothing. When the Messenger of Allah (ﷺ) had said the prayer (and I declare that neither before him nor after him have I seen a leader who gave better instruction than he for whom I would give my father and mother as ransom). I swear that he did not scold, beat or revile me but said: Talking to persons is not fitting during the prayer, for it consists of glorifying Allah, declaring his Greatness. and recitation of the Quran or words to that effect. I said: Messenger of Allah. I was till recently a pagan, but Allah has brought Islam to us; among us there are men who have recourse to Kahins. He said, Do not have recourse to them. I said. There are men who take omens. That is something which they find in their breasts, but let it not turn their way (from freedom of action). I said: Among us there are men who draw lines. He said: There was a prophet who drew lines, so if they do it as they did, that is allowable. I had a maid-servant who tended goats by the side of Uhud and Jawwaniya. One day I happened to pass that way and found that a wolf had carried a goat from her flock. I am after all a man from the posterity of Adam. I felt sorry as they (human beings) feel sorry. So I slapped her. I came to the Messenger of Allah (ﷺ) and felt (this act of mine) as something grievous I said: Messenger of Allah, should I not grant her freedom? He (the Holy Prophet) said: Bring her to me. So I brought her to him. He said to her: Where is Allah? She said: He is in the heaven. He said: Who am I? She said: Thou art the Messenger of Allah. He said: Grant her freedom, she is a believing woman.
Sahih Muslim Book 5, Hadith 39
The Prophet (ﷺ) used to invoke Allah at night, saying, "O Allah: All the
Praises are for You: You are the Lord of the Heavens and the Earth.
All the Praises are for You; You are the Maintainer of the Heaven and
the Earth and whatever is in them. All the Praises are for You; You
are the Light of the Heavens and the Earth. Your Word is the Truth,
and Your Promise is the Truth, and the Meeting with You is the Truth,
and Paradise is the Truth, and the (Hell) Fire is the Truth, and the
Hour is the Truth. O Allah! I surrender myself to You, and I believe
in You and I depend upon You, and I repent to You and with You (Your
evidences) I stand against my opponents, and to you I leave the
judgment (for those who refuse my message). O Allah! Forgive me my
sins that I did in the past or will do in the future, and also the
sins I did in secret or in public. You are my only God (Whom I
worship) and there is no other God for me (i.e. I worship none but
You)."
Narrated Sufyan:
(regarding the above narration) that the Prophet (ﷺ) added, "You are the
Truth, and Your Word is the Truth."
