Key signs include improved character, increased devotion to نماز, avoidance of previous sins, greater humility, and increased charity — نبی کریم said حج Mabroor's reward is Paradise.
The scholars have identified that the primary sign of an accepted حج is a positive transformation in the حاجی's character and worship after returning home. نبی کریم (صلی اللہ علیہ وسلم) said: 'An accepted حج has no reward except Paradise' (Bukhari and Muslim). While only Allah knows with certainty whether a حج is accepted, scholars point to several encouraging indicators.
These signs include: the حاجی feels a greater closeness to Allah and increased love for worship, they maintain or increase their devotion to the five daily نمازs, they exhibit more patience, humility, and kindness in their dealings with others, they actively avoid sins they may have been involved in before حج, they increase in charitable giving and good deeds, and they feel a longing to return to the holy sites. The absence of boasting about the حج is itself considered a positive sign, as sincerity is the foundation of accepted worship.
