Al-Matalib al-'Aliyah 4540 — The description of the resurrection

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said (describing the nature of the horn of the Day of Resurrection): "The reality of the Trumpet (al-Sur) is like a horn, into which it will be blown."
This narration is sahih (authentic) and mawquf (i.e. the statement of a Companion).
