if your saviour is saved, then there is one Saviour, the Saviour of your saviour.

If your saviour is saved, then there is one Saviour, the Saviour of your saviour.

If you were alive at the time of Gideon, you were oppressed by the Midianites.
The military campaign of Gideon saved you; Gideon was your saviour – Gideon, who was overpowered and outnumbered, and was given military salvation by God, his Saviour, your Saviour, and Who you should put your hope for salvation in.

If you were alive at the time of Jonah, peace be upon him, and you were on the boat while the storm swelled the currents against your vessel, you were in danger of going overboard.
The act of Jonah saved you; Jonah was your saviour – Jonah, who was overcome and swallowed entirely —yet who, being delivered from destruction, delivered also those Ninevites by calling them to sincere repentance: to God's Forgiveness— being given complete salvation by God, his Saviour, your Saviour, and Who you should put your hope for salvation in.

If you were alive at the time of Moses, peace be upon him, and you were at the coastline of the Red Sea while the Pharaoh and his men chased after you, then your death was certain.
The miracles of God's Prophet Moses, peace be upon him, saved you; Moses was your saviour – Moses, who was pursued and surrounded by the greatest physical mights on earth, the Pharaoh and water, and was delivered by the Exalted in Might, your Saviour, and Who you should put your hope for salvation in.

If you were alive at the time of Noah, peace be upon him, and you were enshrouded in the civilisation of the disbelief and evildoers, you were living in darkness.
The Ark of your herald of righteousness, Noah, saved you; Noah was your saviour – Noah, who committed himself for centuries to convey God's salvation: who prevailed by having with him the Lord of Mercy, your Saviour, and Who you should put your hope for salvation in.

If you were alive at the time of the Messiah, or any other son of man, and you were seeking the teachings of God and His forgiveness, you were seeking your prophet just as those before you.
The call of God proclaimed by His Messiah –
to know the teaching of worshipping & loving God completely,
and to love thy neighbour as thyself;
to seek His forgiveness
and know that repentance atones for all sins, saved you.
The Messiah was your saviour – the Messiah, who committed his life as a miracle from birth and a sign to humanity —blessed wheresoever he is— and confirming the promises and Forgiveness of the Mighty Forgiver, your Saviour, and Who you should put your hope for salvation in.

If you were alive at the time of Abraham, peace be upon him, and you submitted yourself to the Will of God Almighty as he and his blessed sons (may God's peace be upon them), your salvation and forgiveness were guaranteed.
The Religion of Abraham and the Patriarchs, peace be upon them – which is to make Religion sincerely for God Almighty, singling Him out solely for all worship in truth, inward and outward, word and deed – would be and is your eternal salvation, your saviour just as Abraham saved you and was your saviour.
True success and salvation are in the Religion of Abraham, which is prescribed and perfected by the Bestower of Forms, and revealed again through His final Prophet Muhammad ﷺ.

Now, you are alive at the time of God's final Prophet Muhammad ﷺ, and that success God Most High calls you to is establishing His Religion (the word for which, in Arabic, is "Islam") – to voluntarily and completely submit to the Will of God Almighty, your Saviour, and Who you should put your hope for salvation in.
