Narrated Ibn `Abbas: The Prophet said, "If anyone of you on having sexual relations with his wife said (and he must say it before starting) 'In the name of Allah. O Allah! Protect us from Satan and also protect what you bestow upon us (i.e. the coming offspring) from Satan, and if it is destined that they should have a child then, Satan will never be able to harm that offspring."

Narrated Abu Dhar: Once, while I was in the company of the Prophet, he saw the mountain of Uhud and said, "I would not like to have this mountain turned into gold for me unless nothing of it, not even a single Dinar remains of it with me for more than three days (i.e. I will spend all of it in Allah's Cause), except that Dinar which I will keep for repaying debts." Then he said, "Those who are rich in this world would have little reward in the Hereafter except those who spend their money here and there (in Allah's Cause), and they are few in number." Then he ordered me to stay at my place and went not far away. I heard a voice and intended to go to him but I remembered his order, "Stay at your place till I return." On his return I said, "O Allah's Apostle! (What was) that noise which I heard?" He said, "Did you hear anything?" I said, "Yes." He said, "Gabriel came and said to me, 'Whoever amongst your followers dies, worshipping none along with Allah, will enter Paradise.' " I said, "Even if he did such-and-such things (i.e. even if he stole or committed illegal sexual intercourse)" He said, "Yes."

Narrated Ibn `Abbas: The Prophet said, "If anyone of you, when having sexual relation with his wife, say: 'In the name of Allah. O Allah! Protect us from Satan and prevent Satan from approaching our offspring you are going to give us,' and if he begets a child (as a result of that relation) Satan will not harm it."

Narrated Ibn `Abbas: The Prophet said, "If anyone of you, on having sexual relation with his wife, says: 'O Allah! Protect me from Satan, and prevent Satan from approaching the offspring you are going to give me,' and if it happens that the lady conceives a child, Satan will neither harm it nor be given power over it."

Narrated Ibn `Abbas: The Prophet said, "If anyone of you, when having sexual intercourse with his wife, says: Bismillah, Allahumma jannibni-Sh-Shaitan wa jannib-ish-Shaitan ma razaqtana, and if it is destined that they should have a child, then Satan will never be able to harm him."

Narrated Abu Sa`id Al-Khudri: A bedouin said, "O Allah's Apostle! Inform me about the emigration." The Prophet said, "Waihaka (May Allah be merciful to you)! The question of emigration is a difficult one. Have you got some camels?" The bedouin said, "Yes." The Prophet said, "Do you pay their Zakat?" He said, "Yes." The Prophet said, "Go on doing like this from beyond the seas, for Allah will not let your deeds go in vain."

Narrated Ibn `Abbas: 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."

Narrated Ibn `Abbas: 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).
