Al-Buruj · At-Tariq

85:1 'wa al-sama' dhati al-buruj' and 86:1 'wa al-sama' wa al-tariq' are back-to-back surah openings both beginning with an oath by the sky — al-buruj (the constellations) vs al-tariq (the night-comer).

Hud · Al-Buruj

11:90 'inna rabbi rahimun wadud' and 85:14 'wa huwa al-ghafur al-wadud' both pair Allah's name 'al-Wadud' (the Loving) with another attribute — 11:90 with 'rahimun' and 85:14 with 'al-ghafur' — making 'Wadud' the anchor word for both.
