Assalamu Aleikum, Brother David, what you are doing here is absolutely wrong. A non-muslim asked a question, you intervened by advertising your Aqeeda as good and everyone other's Aqeeda as wrong. This person must have thought: 'These Muslims can't agree on their religion, how can this be a true religion?'. There was a possibility that this person might have said the Shahada. 'La ilaha Il Allah' was enough for this person. You will be responsible on the day of Judgement for this. Waleikum Salam,
