The Prophet used to invoke Allah with the following invocation: 'Rabbi-ghfir-li Khati 'ati wa jahli wa israfi fi `Amri kullihi, wa ma anta a'lamu bihi minni. Allahumma ighfirli khatayaya wa 'amdi, wa jahli wa jiddi, wa kullu dhalika'indi. Allahumma ighrifli ma qaddamtu wa ma akhartu wa ma asrartu wa ma a'lantu. Anta-l-muqaddimu wa anta-l-mu'akh-khiru, wa anta 'ala kulli shai'in qadir.'

Allah's Apostle said, "There will be three types of people whom Allah will neither speak to them on the Day of Resurrection nor will purify them from sins, and they will have a painful punishment: They are, (1) a man possessed superfluous water (more than he needs) on a way and he withholds it from the travelers. (2) a man who gives a pledge of allegiance to an Imam (ruler) and gives it only for worldly benefits, if the Imam gives him what he wants, he abides by his pledge, otherwise he does not fulfill his pledge; (3) and a man who sells something to another man after the `Asr prayer and swears by Allah (a false oath) that he has been offered so much for it whereupon the buyer believes him and buys it although in fact, the seller has not been offered such a price." (See Hadith No. 838, Vol. 3)

Allah's Apostle said, "There are three persons whom Allah will not look at on the Day of Resurrection, nor will he purify them and theirs shall be a severe punishment. They are: -1. A man possessed superfluous water, on a way and he withheld it from travelers. -2. A man who gave a pledge of allegiance to a ruler and he gave it only for worldly benefits. If the ruler gives him something he gets satisfied, and if the ruler withholds something from him, he gets dissatisfied. -3. And man displayed his goods for sale after the `Asr prayer and he said, 'By Allah, except Whom None has the right to be worshipped, I have been given so much for my goods,' and somebody believes him (and buys them). The Prophet then recited: "Verily! Those who purchase a little gain at the cost of Allah's Covenant and their oaths." (3.77)

Ibn `Umar never offered the Duha prayer except on two occasions: (1) Whenever he reached Mecca; and he always used to reach Mecca in the forenoon. He would perform Tawaf round the Ka`ba and then offer two rak`at at the rear of Maqam Ibrahim. (2) Whenever he visited Quba, for he used to visit it every Saturday. When he entered the Mosque, he disliked to leave it without offering a prayer. Ibn `Umar narrated that Allah's Apostle used to visit the Mosque of Quba (sometime) walking and (sometime) riding. And he (i.e. Ibn `Umar) used to say, "I do only what my companions used to do and I don't forbid anybody to pray at any time during the day or night except that one should not intend to pray at sunrise or sunset."

When the Prophet got up at night to offer the night prayer, he used to say: "Allahumma laka l-hamdu; Anta nuras-samawati wal ardi wa man fihinna. wa laka l-hamdu; Anta qaiyim as-samawati wal ardi wa man flhinna. Wa lakaI-hamdu; Anta-l-,haqqun, wa wa'daka haqqun, wa qauluka haqqun, wa liqauka haqqun, wal-jannatu haqqun, wannaru haqqun, was-sa atu haqqun, wan-nabiyyuna huqqun, Mahammadun haqqun, Allahumma laka aslamtu, wa Alaika tawakkaltu, wa bika amantu, wa ilaika anabtu, wa bika Khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akh-khartu, wa ma asrartu, wa ma a'lantu. Anta al-muqaddimu, wa anta al-mu-'akhkhiru. La ilaha il-la anta (or La ilaha ghairuka)"

The Prophet used to invoke Allah, saying, "Allahumma ighfirli khati'ati wa jahli wa israfi fi `Amri, wa ma anta a-'lamu bihi minni. Allahumma ighfirli hazali wa jiddi wa khata'i wa amdi, wa kullu dhalika 'indi."

Another chain reports a similar hadith.

The Prophet used to teach us the Istikhara for each and every matter as he used to teach us the Suras from the Holy Qur'an. (He used to say), "If anyone of you intends to do something, he should offer a two-rak`at prayer other than the obligatory prayer, and then say: 'Allahumma inni astakhiruka bi'ilmika, wa astaqdiruka biqudratika, wa as'aluka min fadlika-l-'azim, fa innaka taqdiru wala aqdiru, wa ta'lamu wala a'lamu, wa anta'allamu-l-ghuyub. Allahumma in kunta ta'lamu anna hadha-lamra khairun li fi dini wa ma'ashi wa 'aqibati `Amri (or said, fi 'ajili `Amri wa ajilihi) fa-qdurhu li, Wa in kunta ta'lamu anna ha-dha-l-amra sharrun li fi dini wa ma'ashi wa 'aqibati `Amri (or said, fi ajili `Amri wa ajilihi) fasrifhu 'anni was-rifni 'anhu wa aqdur li alkhaira haithu kana, thumma Raddani bihi," Then he should mention his matter (need).

The people said, "O Allah's Apostle ! How may we send Salat on you?" He said, "Say: Allahumma Salli 'ala- Muhammadin wa azwajihi wa dhurriyyatihi kama sal-laita 'ala `Ali Ibrahim; wa barik 'ala Muhammadin wa azwajihi wa dhurriyyatihi kamabarakta 'ala `Ali Ibrahim innaka hamidun majid."

In the year of Hajjat-ul-Wada` the Prophet visited me when I fell ill and was about to die because of that illness. I said, "O Allah's Apostle! I am very ill as you see, and I am a rich man and have no heir except my only daughter. Shall I give 2/3 of my property in charity?" He said, "No." I said, "Shall I then give one half of it in charity?" He said, "O Sa`d! Give 1/3 (in charity) and even 1/3 is too much. No doubt, it is better to leave your children rich than to leave them poor, reduced to begging from others. And Allah will reward you for whatever you spend with the intention of gaining Allah's Pleasure even if it were a mouthful of food you put into your wives mouth." I said, "O Allah's Apostle! Am I to be left behind (in Mecca) after my companions have gone?" He said, "If you should be left behind, you will be upgraded and elevated for every deed you will do with a desire to achieve Allah's Pleasure. I hope that you will live long so that some people will benefit by you while others will be harmed. O Allah! Please fulfill the migration of my companions and do not make them turn back on their heels. But (we feel sorry for) the unlucky Sa`d bin Khaulah." Allah's Apostle lamented his death in Mecca.
