Descendance of the prophets is a matter of values rather than physiques; in this context, the Almighty says:

{ وَإِذِ ابْتَلَىٰ إِبْرَاهِيمَ رَبُّهُ بِكَلِمَاتٍ فَأَتَمَّهُنَّ ۖ قَالَ إِنِّي جَاعِلُكَ لِلنَّاسِ إِمَامًا ۖ قَالَ وَمِن ذُرِّيَّتِي ۖ قَالَ لَا يَنَالُ عَهْدِي الظَّالِمِينَ}

(And [mention, O Muhammad], when Abraham was tried by his Lord with commands and he fulfilled them. [Allah] said, “Indeed, I will make you a leader for the people.” [Abraham] said, “And of my descendants?” [Allah] said, “My covenant does not include the wrongdoers.”) (Al-Baqara: 124)

Thus, all the prophets mentioned are descendants of Abraham (PBUH) with the exception if the wrongdoers who don’t carry the same values. This is what’s meant by this verse.

( وَاللَّهُ سَمِيعٌ عَلِيمٌ … ) (…And Allah is Hearing and Knowing): It’s the greatness of the Holy Quran that Allah (swt) says (And Allah is Hearing and Knowing.) when talking about the descendance while we expect the verse to be concluded with (and Allah is Knowing and Wise). The reason behind that is that the talk is about the descendants of the prophets. Abraham and Ishamel (PBUH) once supplicated:

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

(Our Lord, and make us Muslims [in submission] to You and from our descendants a Muslim nation [in submission] to You. And show us our rites and accept our repentance. Indeed, You are the Accepting of repentance, the Merciful.) (Al-Baqara: 128)

Zechariah also supplicated:

 {رَبِّ هَبْ لِي مِن لَّدُنكَ ذُرِّيَّةً طَيِّبَةً ۖ إِنَّكَ سَمِيعُ الدُّعَاءِ}

(My Lord, grant me from Yourself a good offspring. Indeed, You are the Hearer of supplication.”) (Aal-Imran: 38)

Therefore, here we have (And Allah is Hearing and Knowing.) because the Almighty has heard the supplications of Abraham, Ishamel, Zechariah, and all the prophets who supplicated to the Him for their progeny. The Almighty knows well where to send His message, however.
