8. Do you know the most expected and accepted dua of Ibrahim (AS)?

السلام عليكم ورحمة الله وبركاتة 

بِسْمِ ٱللَّٰهِ ٱلرَّحْمَٰنِٱلرَّحِيمِ

Remember what Allah Subhanahuthala proclaimed in Holy Quran: "When the Lord of Ibrahim (AS) [i.e., Allah] tried him with (certain) Commands, which he fulfilled. Allah said (to him), “Verily, I am going to make you a leader (Prophet) of mankind.”

[Ibrahim (AS)] asked, “And of my offspring (to make leaders)?” (Allahuthala) answered, “My Covenant (Prophethood, etc.) includes not the wrong-doers.” [2:124]. He prayed, “Our Lord! Send amongst them a Messenger of their own, who shall recite unto them Your Verses and instruct them in the Book and Al-Hikmah and sanctify them. Verily! You are the All-Mighty, the All-Wise.” [2:129]

Allahuthala accepted his prayer and made in his offspring the Imams, which you are familiar about:

Ismail (AS)

Ishaq (AS)

Yaqub (AS)

His 12 sons,

Yusuf (AS)

Ayub (AS)

Shuayb (AS)

Musa (AS)

Harun (AS)

Nabi Uzaer

Many Prophets whose name was not mentioned in Quran,

Dawud (AS)

Sulaiman(AS)

Isa ibn Marium (AS)

Muhammad (SAW)

Allah accepted Ibrahim’s supplication, although He had full knowledge beforehand that it will occur by His decree. A hadhees about  Messenger of Allah says, when he was asked, “O Messenger of Allah! Tell us about how your Prophet hood started.” He said, "I am the supplication of my father Ibrahim (AS), the good news of Isa ibn Marium (AS), and my mother saw a light that radiated from her which illuminated the castles of Ash-Sham (Syria)." 

Kindly pray for you and your offspring too! If you totally submit to Allah; perform all the duties commanded to you whole heartedly; do lot of good deeds and pray for your offspring, Allahuthala certainly answer your prayers and make your family a successful one.
