The word(s) "weaker" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Say: As for him who remains in error, the Beneficent Allah will surely prolong his length of days, until they see what they were threatened with, either the punishment or the hour; then they shall know who is in more evil plight and weaker in forces

(2) Until when they see what they are threatened with, then shall they know who is weaker in helpers and fewer in number.
