عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ لِكُلِّ دَاءٍ دَوَاءٌ فَإِذَا أَصَابَتْ دَوَاءٌ الدَّاءَ بَرَأَ بِإِذْنِ اللَّهِ تَعَالَى
Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him and his family) said: For every disease there is a cure; when the medicine matches the disease, by the command of Allah, the patient becomes healthy.
