وَمَنْ صَلَّى الْمَغْرِبَ فِي الطَّرِيقِ لَمْ تُجْزِهِ عِنْدَ أَبِي حَنِيفَةَ وَمُحَمَّدٍ.
Translation: Whoever prays Maghrib on the road has not discharged it according to Abu Hanifah and Muhammad.
This is a specific Hanafi legal position quoted by al-Quduri. For example, a pilgrim may pray Maghrib en route from Arafat before reaching Muzdalifah; under the named view, that performance does not discharge the prescribed prayer.
The text explicitly names Abu Hanifah and Muhammad. It should not be stated as an unconditional ruling for all jurists or all exceptional circumstances.
