Explanation

Dua is supplication – asking Allah directly for needs. Different from salat (formal prayer). No set times or rituals required; can make dua anytime, anywhere. Allah promises to respond (Quran 40:60).

Conditions for acceptance: sincerity (only to Allah), lawful request, patience, certainty Allah hears, not asking while committing sin, and lawful income (Prophet said Allah does not accept dua from unlawful earnings).

Best times: last third of night, between adhan and iqama, during prostration, after obligatory prayer, Friday afternoon. Response may be: yes, wait, or something better. Trust Allahs wisdom.
