How can multiple intentions be combined in a single act to receive reward for each intention, with examples?

Multiple intentions can be combined in a single act of worship to gain greater reward and recompense, such as praying in the mosque with the intention of its reward, increasing the congregation of Muslims, and populating the houses of Allah. This is indicated by the Prophet's (peace be upon him) saying: "Indeed, actions are by intentions, and indeed every person will have what he intended." So, whoever is guided to good intentions in his actions has been granted a great bounty.
