when there shrouded the lote tree that which shrouded [it].This means: ⸢that which shrouded⸣ the lote tree (ay mā yaghshā al-shajara) was from the light of Muḥammad as he worshipped. It could be likened to golden moths, which God sets in motion towards Him from the wonders of His secrets. All this is in order to increase him [Muḥammad] in firmness (thabāt) for the influx [of graces] (mawārid) which he received [from above].
