[3]. Muhammad, God's Messenger (ﷺ) said: “He is not a believer who seeks omens or has omens interpreted for him; or who practices fortunetelling or has his fortune told; or who practices magic or goes to have it done for him; and whoever goes to a soothsayer and believes in what he says has disbelieved in (God and) His Scripture." Omens are not true. Omens are not from Allāh (God). So one should not listen to any religion, scriptures, tradition, customs, or parents and elders, that give authenticity to omens.
[5]. When this verse ‘So glorify the Name of your Lord, the Most Great’ was revealed, the Prophet ﷺ said: ‘Put it in your bowing.’ And when the verse ‘Glorify the Name of your Lord, the Most High’ (87:1) was revealed, he said: ‘Put it in your prostration.’
Then the Prophet Muhammad ﷺ, while he was bowing down in the prayer, he would say: (Subhāna Rabbiyal Azim); “Glorious is 'Allāh' my Lord, the Magnificent” and while prostrating: (Subhāna Rabbiyal A’la) ‘Glorious is 'Allāh' my Lord, the Most High.’
Exalting Allāh, Lord of the epeople, King of the people, God of the people, praising His Name. Great is Allāh the Lord and most worthy of praise; His greatness no one can encompass."
And it is narrated to say between the two prostrations: "O Allāh, forgive me [my sins], have mercy on me, guide me, grant me well-being, and provide for me my provision."
You may also say in your supplication in the prostration or in the last part of the prayer before the tasleem: O Allāh' forgive us our sins, as we forgive those who sin against us. Lead us not into temptation, but deliver us from evil. For yours is the kingdom, and the power, and the glory forever.
