"The Book of Monotheism which is the Right of Allah upon His Servants "
Praise be to Allah, and may Allah’s blessings and peace be upon our Prophet Muhammad and his family and Companions.
And the Qur’anic verse that says: {I have not created the jinn and mankind except to worship Me.} [Surat adh-Dhāriyāt: 56]
And the verse that says: {Indeed, We sent to every community a messenger, [saying], “Worship Allah and shun false gods.”} [Surat an-Nahl: 36]
And the verse that says: {Your Lord has ordained that you worship none but Him, and show kindness to parents. If one or both of them reach old age in your care, do not say to them a word of annoyance nor scold them, rather speak to them noble words, and lower to them the wing of humility out of mercy, and say, “My Lord, have mercy upon them as they raised me when I was small.”} [Surat al-Isrā’: 23-24]
And the verse that says: {Worship Allah and do not associate any partners with Him.} [Surat an-Nisā’: 36]
And the verse that says: {Say [O Prophet], “Come, I will recite to you what your Lord has forbidden to you: do not associate any partners with Him, and honor your parents. Do not kill your children for fear of poverty, for We provide for you and for them. Do not approach shameful acts, whether openly or in secret. Do not kill the soul sanctified by Allah, except lawfully. This is what He commands you, so that you may understand. Do not approach the orphan’s property, except to improve it, until he attains maturity. Give full measure and weight with justice. We do not burden any soul beyond what it can bear. And maintain justice when you speak, even if it be about a close relative. And fulfill the covenant of Allah. This is what He commands you, so that you may take heed. This is My straight path; follow it and do not follow other ways, lest they lead you away from His way. This is what He commands you, so that you may become righteous.”} [Surat al-An‘ām: 151-153]
- Ibn Mas‘ūd (may Allah be pleased with him) said: Whoever wants to see Muhammad’s instruction upon which his seal was, let him recite the verses that say: {Say [O Prophet], “Come, I will recite to you what your Lord has forbidden to you: do not associate any partners with Him} Until the verse that says: {This is My straight path; follow it and do not follow other ways, lest they lead you away from His way. This is what He commands you, so that you may become righteous.”} [Surat Al-An‘ām: 151-153]
- Mu‘ādh ibn Jabal (may Allah be pleased with him) reported: I was riding behind the Prophet (may Allah’s peace and blessings be upon him) on a donkey, and he said to me: “O Mu‘ādh, do you know what the right of Allah upon His servants is, and what the right of the servants upon Allah is?” I said: “Allah and His Messenger know best.” He said: “The right of Allah upon the servants is that they worship Him and associate nothing with Him; and the right of the servants upon Allah is that He does not punish those who associate nothing with Him.” I said: “O Messenger of Allah, shall I give people glad tidings?” He said: “Do not give them glad tidings lest they would rely upon it.” [Narrated by Al-Bukhāri and Muslim]
