Translation:

104. Say: "O ye men! if ye are in doubt as to my religion (behold!) I worship not what ye worship other than Allah But I worship Allah Who will take your souls (at death): I am commanded to be (in the ranks) of the Believers.

Notes (Tafseer)

1485. Other people may hesitate, or doubt, or wonder. But the righteous man has no doubt in his own mind, and he declares his Faith clearly and unambiguously to all, as did Al-Mustafa.

1486. The worship of the One and True God is not a fancy worship, to be arrived at merely by reasoning and philosophy. It touches the vital issues of life and death-which are in His hands and His alone.

1487. Nor is the worship of One God an invention of the Prophet. It comes as a direct command through him and to all.

1488. Individual Faith is good, but it is completed and strengthened by joining or forming a Righteous Society, in which the individual can develop and expand. Islam was never a religion of monks and anchorites. It laid great stress on social duties, which in many ways test and train the individual's character.
