وَقَدْ تُضَافُ إِلَى الْمُفْرَدِ، كَقَوْلِ الشَّاعِرِ: «أَمَا تَرَى حَيْثَ سُهَيْلٍ طَالِعًا».
Translation: It can also be annexed to a single noun, as in the poet’s line asking whether one sees where Suhayl is rising.
The source notes a poetic/exceptional construction where ḥaythu takes a single noun instead of a clause. This should not be generalized indiscriminately in prose.
Parsing the poetic example: amā: interrogative sequence; tarā: imperfect with implied “you”; ḥaytha: accusative place adverb in this special poetic construction and muḍāf; Suhaylin: genitive complement; ṭāliʿan: accusative circumstantial descriptor of Suhayl.
