What must a Muslim do to reach Firdaus, and must he accumulate as many good deeds as possible, or what? And what is the authenticity of the hadith: "Whoever seeks forgiveness for believing men and women, for him there is a good deed for every believing man and woman"? And must a Muslim accumulate as much reward as possible, even if that means abandoning other acts of worship that yield less reward? And does one who causes a person to embrace Islam receive the reward for that person's acts of worship? And does the inventor of something beneficial receive the reward for its good use until the Day of Judgment?

The path to high ranks and the Gardens of Firdaus is faith and righteous deeds, as detailed in Surah Al-Mu'minoon. Deeds with multiplied rewards are commendable for their doer and indicate their high aspiration, earning them greater rewards. The Companions asked the Prophet, peace be upon him, about the best deeds. Examples include specific dhikrs like "Subhanallahi wa bihamdihi adada khalqihi, wa ridha nafsihi, wa zinata arshihi, wa midada kalimatihi" (Glory be to Allah and praise be to Him, as many times as the number of His creation, in accordance with His pleasure, equal to the weight of His Throne, and equal to the ink of His words), and "Subhanallah adada ma khalaq, Subhanallah mil'a ma khalaq..." (Glory be to Allah as many times as He created, Glory be to Allah as much as He created...). Focusing on deeds with multiplied rewards to increase recompense is valid, provided it does not lead to neglecting a specific Sunnah. The multiplication of reward occurs due to a distinction in the deed, its place, its time, or the doer. Seeking forgiveness for believing men and women brings good deeds equivalent to their number. And whoever causes a person to embrace Islam, or invents something that aids people in worship, will receive the reward for their deeds.
