He عَـلَيْـهِ الـسَّـلَام then made the following Du’a in the court of Allah Almighty:

رَبَّنَا وَ ابْعَثْ فِیْهِمْ رَسُوْلًا مِّنْهُمْ

(Translation of Kanz-ul-Iman: 'O our Lord, and send amongst them a Messenger from themselves).

[Kanz-ul-Iman (Translation of Quran)] (Part 1, Surah Al-Baqarah, Verse 129)

Meaning, ‘O Allah! May a group of believers always remain among my offspring, and O Allah! Send the Final Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم in this group of believers.’ No doubt, this Du’a of Sayyiduna Ibrahim عَـلَيْـهِ الـسَّـلَام was accepted. The forefathers of the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم were all people of Iman and believers. (Tafseer-e-Rooh-ul-Bayan, vol. 5, pp. 518)

Heavenly whale

Sayyiduna Allamah Isma’eel Haqqi رَحْمَةُ الـلّٰـهِعَلَيْه narrates in Tafseer Rooh-ul-Bayan: ‘Sayyiduna Yunus عَـلَيْـهِ الـسَّـلَام remained in the belly of the whale for three, seven or forty days, hence, that whale will go to Paradise.

(Dalaail-un-Nubuwwah, pp. 28, Hadees 15)

The Blessed Parents are people of Paradise

O devotees of the Prophet! Think for a moment! If the whale in whose belly the Prophet of Allah, Sayyiduna Yunus عَـلَيْـهِ الـسَّـلَام remained for a few days will go to Paradise, then what can be said about the blessed womb in which the leader of Sayyiduna Yunus عَـلَيْـهِ الـسَّـلَام, Sayyiduna Muhammad صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم remained in for several months. How is it possible that Sayyidatuna Aaminah رَضِیَ اللهُ عَنْهَا left this world upon Kufr مَعَاذَاللّٰہ and was subjected to the punishment of the grave! Undoubtedly, every moment of the lives of the blessed parents رَضِىَ الـلّٰـهُ عَـنْهُما of the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم was spent upon Tawheed (i.e. in a state of Iman), and they are people of Paradise. In fact, all of the forefathers of the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم were upon the truth, just as the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said: ‘I continued to be transferred from the loins of pure men to the wombs of pure women.’
