Reports have been narrated regarding the virtue of the prayer of Ishraq; how authentic are they, and if they are not authentic, is it a recommended practice?

The questioner : In the name of Allah, the Most Gracious, the Most Merciful.
His EminenceThe Shaykh : Reports have been narrated regarding the virtue of the prayer of Ishraq; how authentic are these reports? And if they are not authentic, is it a recommended practice? May Allah reward you with good.

The Shaykh : The scholars differed regarding the sunnah of the Dhuha prayer: is it a recommended practice, an innovation, or is there a detailed ruling? The closest opinion is that there is a detailed ruling: that is, one who is accustomed to standing in night prayer does not persist in it, and one who is not accustomed to standing in night prayer persists in it. This is the choice of the Shaykh al-Islam (may Allah have mercy on him).
But I say: it came in the hadith: So because of this hadith, I see that it is incumbent upon the person to persist in the two rak'ahs of Dhuha, because they serve as a substitute for all the almsgiving that is obligatory upon him. Every day the sun rises, every limb of yours is an almsgiving, and you are compelled to it. The limbs are three hundred and sixty, so three hundred and sixty almsgivings are obligatory upon you. But it is not only almsgiving of wealth; every word that brings one closer to Allah is almsgiving, and every deed that brings one closer to Allah is almsgiving. The tasbih is almsgiving, and the takbir is almsgiving. Removing a harmful object from the path is almsgiving, and helping a rider to mount his mount is almsgiving. But two rak'ahs that one prays in the Dhuha suffice for all of that. So because of this hadith, I see that one should persist in it so that these two rak'ahs serve as expiation for all the almsgivings.
