قَالَ أَبُو عَبْدِ اللَّهِ ع اطْلُبُوا الدُّعَاءَ فِي أَرْبَعِ سَاعَاتٍ عِنْدَ هُبُوبِ الرِّيَاحِ وَ زَوَالِ الْأَفْيَاءِ[1] وَ نُزُولِ الْقَطْرِ وَ أَوَّلِ قَطْرَةٍ مِنْ دَمِ الْقَتِيلِ الْمُؤْمِنِ فَإِنَّ أَبْوَابَ السَّمَاءِ تُفَتَّحُ عِنْدَ هَذِهِ الْأَشْيَاءِ.
"Seek supplication at four times: during the blowing of the winds, the fading of the shadows, the descent of rain, and when the first drop of blood from a martyred believer has spilled, for indeed the gates of heaven open at these times."
