Musannaf Ibn Abi Shaybah 31727 — A man supplicating while standing

Abd al-Rahman bin Yazid said that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Two things are innovation: that a man, after finishing his prayer, should stand facing the Qiblah and supplicate; and that he should perform the second prostration and then think it an obligation upon him to press his buttocks to the ground before rising."

Sayyiduna Abu Ayyub (may Allah be pleased with him) said: I used to be in a small storeroom of mine, and a shape-changing jinn would come to me, so I complained about this to the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) said: "When you see it, say: 'In the name of Allah, answer the Messenger of Allah (peace and blessings be upon him).'" He said: When it came, I said these words and seized it. It said to me: "I will certainly not come back." So I let it go. I went to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said to me: "What became of your captive?" He said: "I seized it, and it said: 'I will not come back.' Then I let it go." Then he (peace and blessings be upon him) said: "It will certainly come back." He said: I seized it two or three times. Each time it said: "I will not come back." And he would go to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) would say: "What became of your captive?" He would say: "I seized it, and it said: 'I will not come back.'" Then he (peace and blessings be upon him) would say: "It will certainly come back." He said: Then I seized it, and it said: "Let me go and I will teach you something; when you recite it, nothing will come near you. It is Ayat al-Kursi." So he came to the Prophet (peace and blessings be upon him) and informed him (peace and blessings be upon him) of this, and he (peace and blessings be upon him) said: "It has told the truth, although it is a liar."
