It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said:“(If) a donkey, a woman, or a black dog passes in front of a person praying, the prayer must be repeated.”I (Abdullah bin Samit) asked: What is the reason for specifying the black dog (excluding) yellow and red dogs? I said: I asked the Messenger of Allah (peace and blessings be upon him) the same question that you have asked me, and he (peace and blessings be upon him) replied:“The black dog is a devil.”

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), he says that the Messenger of Allah (peace and blessings be upon him) said: "When a man performs prayer, he should wear two garments, because Allah is more deserving that adornment be adopted for Him."

It is narrated from Sayyidah Rabi’ bint Mu’awwidh (may Allah be pleased with her) that the Noble Prophet (peace and blessings of Allah be upon him) said: "When people offer the funeral prayer for the deceased and praise him, Allah the Exalted says: I have enforced the testimony of My servants based on the good deeds which they know, and I have forgiven the bad deeds which they do not know."

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings of Allah be upon him) said: "When the companion of the Qur'an stands in prayer during the hours of the night and day and recites the Qur'an, he remembers it; otherwise, if he does not stand (in prayer), he forgets it."

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that when the Messenger of Allah, peace and blessings be upon him, would begin the prayer, he would recite: «سبحانك اللهم وبحمدك وتبارك اسمك، وتعالى جدك ولا إله غيرك» "O Allah! You are Pure with Your praises, blessed is Your name, exalted is Your status, and there is no true deity except You."

It is narrated from Sayyiduna Ibn Mughaffal Muzani (may Allah be pleased with him), he states that the Noble Prophet (peace and blessings be upon him) said: "When you find the Imam in the state of prostration, then perform prostration with him; if you find him in the state of bowing, then bow with him; and if you find him standing, then begin standing with him. But do not count the prostrations unless you have caught the bowing."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) says: It is Sunnah that during the sitting between the two prostrations in prayer, you place your buttocks on your heels.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade iq‘a’ and tawarruk in prayer.

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: We did not know what to say (in prayer when sitting after two) rak'ahs, except that we used to glorify Allah, proclaim His greatness, and praise Him. Indeed, Muhammad, the Messenger of Allah (peace and blessings be upon him), was taught the beginning and end of all goodness. So (one day) the Prophet (peace and blessings be upon him) said: "When you sit after two rak'ahs, recite: All verbal, physical, and financial acts of worship are for Allah. O Prophet! Peace be upon you, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no deity worthy of worship except Allah, and Muhammad (peace and blessings be upon him) is His servant and Messenger. (After reciting this tashahhud) he should choose whatever supplications he likes."

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "After every two rak‘ahs, the Tashahhud is to be recited, and supplication for peace is to be made for the prophets and the righteous servants of Allah who follow them."
