Asalamu 'aleykum wa Rahamatollahi wa Barakato.

This app could contain stories of other Prophets and other Muslims, it could be renamed "Seerah: life of the Prophets and companions" or "Seerah: life of the Prophets and their followers".

So it can contain a lot of seerah books, that would be very beneficial Incha'Allah, for example you could add Qisas al-Anbiya (stories of the Prophets) by ibn Kathir.

This are some ideas, Incha'Allah you will expand this further.

May Allah guide and reward all of you.
