When My servants question thee concerning Me, then surely I am nigh. I answer the prayer of the suppliant when he crieth - Quraan 2:186 (1)

"...Our Lord! Accept from us (this duty). Lo! Thou, only Thou, art the Hearer, the Knower,

Our Lord! And make us submissive unto Thee and of our seed a nation submissive unto Thee, and show us our ways of worship, and relent toward us. Lo! Thou, only Thou, art the Relenting, the Merciful,

Our Lord! And raise up in their midst a messenger from among them who shall recite unto them Thy revelations, and shall instruct them in the Scripture and in wisdom and shall make them grow. Lo! Thou, only Thou, art the Mighty, Wise. " Quraan 2:127-129

رَبَّنَا تَقَبَّلْ مِنَّا إِنَّكَ أَنتَ السَّمِيعُ الْعَلِيمُ

رَبَّنَا وَاجْعَلْنَا مُسْلِمَيْنِ لَكَ وَمِن ذُرِّيَّتِنَا أُمَّةً مُّسْلِمَةً لَّكَ وَأَرِنَا مَنَاسِكَنَا وَتُبْ عَلَيْنَا إِنَّكَ أَنتَ التَّوَّابُ الرَّحِيمُ

رَبَّنَا وَابْعَثْ فِيهِمْ رَسُولاً مِّنْهُمْ يَتْلُو عَلَيْهِمْ آيَاتِكَ وَيُعَلِّمُهُمُ الْكِتَابَ وَالْحِكْمَةَ وَيُزَكِّيهِمْ إِنَّكَ أَنتَ الْعَزِيزُ الْحَكِيمُ

البقرة : ١٢٧-١٢٩

That was the supplication of Abraham & Ishmael while rebuilding Al-Kaaba.

Has the supplication been fulfilled?
Apparently yes. Mohammad who was from Mecca was sent as a Messenger, a massive Muslim nation was descended from Ishmael, and around two millions of Muslims perform pilgrimage to Mecca every year!
