Allah's Apostle said, "If anyone of you, when intending to have a sexual relation (sleep) with his wife, says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would never harm that child, should it be ordained that they will have one. (Because of that sleep).

The Prophet said, "If anyone of you, when intending to have a sexual intercourse with his wife, says: 'Bismillah, Allahumma jannibna-sh-shaitan, wa jannibi-sh-shaitan ma razaqtana,' and if the couple are destined to have a child (out of that very sexual relation), then Satan will never be able to harm that child."

"When the "Surat-An-Nasr", 'When comes the Help of Allah and the conquest,' had been revealed to the Prophet he did not offer any prayer except that he said therein, "Subhanka Rabbana wa bihamdika; Allahumma ighfirli (I testify the Uniqueness of our Lord, and all the praises are for Him: O Allah, forgive me!")

The Prophet used to say at the time of difficulty, 'La ilaha il-lallah Al-`Alimul-Halim. La-ilaha illallah Rabul- Arsh-al-Azim, La ilaha-il-lallah Rabus-Samawati Rab-ul-Ard; wa Rab-ul-Arsh Al- Karim.' (See Hadith No. 356 and 357, Vol. 8)

Yahya related to me from Malik from Abu'z Zubayr al-Makki from Tawus al-Yamani from Abdullah ibn Abbas that the Messenger of Allah, may Allah bless him and grant him peace, used to say, when he rose for prayer in the middle of the night, "O Allah, praise belongs to You. You are the light of the heavens and the earth and praise belongs toYou.You are the Sustainer of the heavens and the earth and praise belongs to You. You are the Lord of the heavens and the earth and whoever is in them. You are the Truth, and Your words are true. Your promise is true, and the meeting with You is true. The Garden is true and the Fire is true and the Hour is true. O Allah, I submit toYou and I accept You and I trust in You and I turn to You and I argue by You and I summon toYou for judgement. Forgive me what I have sent before me and what I have left behind, what I have kept secret and what I have proclaimed, You are my god - there is no god but You."

Allahumma laka'l-hamdu anta nuru's-samawati wa'l-ardi, wa laka'l-hamdu anta qayamu's-Samawati wa'l-ardi, wa laka'l-hamdu anta rabbu's-Samawati wa'l-ardi,wamanfihina.Anta'l-haqqu,waqawluka'lhaqqu, wa waduka'l-haqqu, wa liqa'uka haqqun, wa jannatu haqqun, wa naru haqqun, wa sactu haqqun. Allahumma laka aslamtu, wa bikaamantu, waalayka tawakaltu, wa ilayka anabtu, wa bika khasamtu, wa ilayka hakamtu, fa'ghfirliy ma qadamtu wa akhartu wa asrartu, wa alantu. Anta ilahiy, la ilaha illa ant.

[Abu Dawud and At-Tirmidhi].

A man passed by the Prophet (sal Allaahu alayhi wa sallam ) while he was urinating, and saluted him. The Prophet (sal Allaahu alayhi wa sallam) did not return the salutation to him.

Abu Dawud said : It is narrated on the authority of Ibn 'Umar that the Prophet (sal Allaahu alayhi wa sallam) performed tayammum, then he returned the salutation to the man.

The Prophet used to say frequently in his bowing and prostrations "Subhanaka l-lahumma Rabbana wa bihamdika, Allahumma ghfir li" (Exalted [from unbecoming attributes] Are you O Allah our Lord, and by Your praise [do I exalt you]. O Allah! Forgive me). In this way [??] he was acting on what was explained to him in the Holy Qur'an.

When the Prophet said, "Sami`a l-lahu liman hamidah," (Allah heard those who sent praises to Him), he would say, "Rabbana wa laka l-hamd." On bowing and raising his head from it the Prophet used to say Takbir. He also used to say Takbir on rising after the two prostrations. (See Hadith No. 656).

(The clerk of Al-Mughira) Muawiya wrote to Al-Mughira 'Write to me what you have heard from Allah's Apostle.' So he (Al-Mughira) wrote to him: Allah's Prophet used to say at the end of each prayer: "La ilaha illalla-h wahdahu la sharika lahu, lahul Mulku, wa lahul Hamdu wa hula ala kulli shai'in qadir. 'Allahumma la mani' a lima a'taita, wala mu'tiya lima mana'ta, wala yanfa'u dhuljadd minkal-jadd." He also wrote to him that the Prophet used to forbid (1) Qil and Qal (idle useless talk or that you talk too much about others), (2) Asking too many questions (in disputed Religious matters); (3) And wasting one's wealth by extravagance; (4) and to be undutiful to one's mother (5) and to bury the daughters alive (6) and to prevent your favors (benevolence to others (i.e. not to pay the rights of others (7) And asking others for something (except when it is unavoidable).

My father got me married to a lady of a noble family, and often used to ask my wife about me, and she used to reply, "What a wonderful man he is! He never comes to my bed, nor has he approached me since he married me." When this state continued for a long period, my father told the story to the Prophet who said to my father, "Let me meet him." Then I met him and he asked me, "How do you fast?" I replied, "I fast daily," He asked, "How long does it take you to finish the recitation of the whole Qur'an?" I replied, "I finish it every night." On that he said, "Fast for three days every month and recite the Qur'an (and finish it) in one month." I said, "But I have power to do more than that." He said, "Then fast for three days per week." I said, "i have the power to do more than that." He said, "Therefore, fast the most superior type of fasting, (that is, the fasting of (prophet) David who used to fast every alternate day; and finish the recitation of the whole Qur'an In seven days." I wish I had accepted the permission of Allah's Apostle as I have become a weak old man. It is said that `Abdullah used to recite one-seventh of the Qur'an during the day-time to some of his family members, for he used to check his memorization of what he would recite at night during the daytime so that it would be easier for him to read at night. And whenever he wanted to gain some strength, he used to give up fasting for some days and count those days to fast for a similar period, for he disliked to leave those things which he used to do during the lifetime of the Prophet.
