Sayyiduna Abu Hurayrah (radiyallahu ‘anhu) reports that Nabi (sallallahu ‘alayhi wa sallam) said: ‘When a person does not have enough good deeds to reach a certain level in Jannah, but Allah Ta’ala wants him to attain that level, then Allah Ta’ala tests him and puts him through difficult trials so that Allah may make him reach that level (in Jannah)’ (Sahih Ibn Hibban; Al Ihsan, Hadith: 2908) Similar narrations have also been recorded in Mustadrak Hakim, Musnad Ahmad, Musnad Abu Ya’la and Al Mu’jamul Kabir of Tabarani. (Refer: Mustadrak Hakim, vol. 1 pg. 344 and Majma’uz Zawaid, vol. 2 pg. 292)
Malik related to me that he heard that someone said to Luqman, "What has brought you to what we see?" meaning his high rank. Luqman said, "Truthful speech, fulfilling the trust, and leaving what does not concern me."
