What is the ruling on the adhan for the one who prays alone?

The Shaykh : Did they hear the adhan before, or did they not hear it? Well, if they are in the same town where the adhan is being called, then the town's adhan is sufficient. But if they are in the desert and then they reach the town, they should call the adhan. However, they should not call it with a loudspeaker; rather, they should call it in the place where they are praying. For example, if a person comes from Riyadh and the time for prayer enters while he is on the road, and he reaches the town, then he should call the adhan if they are praying in congregation. Do you understand? But if they are in the same town, the town's adhan is sufficient. For the one who prays alone, calling the adhan is a recommended practice (sunnah) for him. Its ruling is the same as for the congregation. For instance, if he is in the desert and not in the town, he should call the adhan as a recommended practice.
