[1/222] رجال الكشي: محمد بن مسعود، عن علي بن الحسن، عن معمر بن خلاد قال: قال أبو الحسن الرضا عليه السلام: إن رجلا من أصحاب علي عليه السلام يقال له قيس كان يصلي فلما صلى ركعة أقبل أسود (سالخ) فصار في موضع السجود، فلما نحى جبينه عن موضعه تطوق الأسود في عنقه ثم أنساب في قميصه (وذهب ولم يقطع صلاته)، و إني أقبلت يوما من الفرع، فحضرت الصلاة فنزلت فصرت إلى ثمامة، فلما صليت ركعة أقبل أفعى نحوي، فأقبلت على صلاتي لم أخففها و لم ينتقص منها شي‏ء فدنا مني ثم رجع إلى ثمامة، فلما فرغت من صلاتي و لم أخفف دعائي دعوت بعضهم معي فقلت دونك الأفعى تحت الثمامة، و من لم يخف إلا الله كفاه

1. [1/222] Rijal al-Kashshi: Muhammad b. Masud from Ali b. al-Hasan from Mu’ammar b. Khallad who said: Abu al-Hasan al-Ridha عليه السلام said: A man from among the companions of Ali عليه السلام called Qays was praying, after he finished the first unit a large black snake came and crawled onto the place of prostration, when he [Qays] lowered his forehead near it the snake latched onto his neck, encircled it and left slithering through his inner garment [but he did not break his prayer]! I [the Imam] was returning one day from al-Fur` [a place between Makka and Madina] when the time of prayer entered. I dismounted and proceeded near a Thumama [panic grass] shrub. When I completed a single unit a snake came near me, but I continued with my prayer and did not shorten it in any way nor did I allow any deficiencies to come into it. It came near me then returned to the shrub. Only when I had completed my prayer and followed it up by my normal supplication did I call the one who was with me and said: Keep away from the snake under the shrub. Whoever fears none except Allah then He suffices for him.
