The word(s) "weaker" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) Say, "Whoever is in error - let the Most Merciful extend for him an extension [in wealth and time] until, when they see that which they were promised - either punishment [in this world] or the Hour [of resurrection] - they will come to know who is worst in position and weaker in soldiers."

(2) [The disbelievers continue] until, when they see that which they are promised, then they will know who is weaker in helpers and less in number.
