﴿ أَن لَّا يَدْخُلَنَّهَا ٱلْيَوْمَ عَلَيْكُم مِّسْكِينٌۭ ﴾

“"Indeed, no needy person shall enter it today [and come] upon you [unawares],"”

‘No needy person shall today come to you in it’ this constitutes the explication of the preceding verse; or else an relates to the verbal action to be understood to mean bi-an.
