Hadith 688:16
Safwan ibn ‘Isa narrated to us, Ibn ‘Ajlan informed us, from Sa‘id al-Maqburi, from ‘Umar ibn al-Hakam, from ‘Abdullah ibn ‘Anamah, who said: I saw ‘Ammar ibn Yasir enter the mosque and pray, and he made the prayer light. He said: When he left, I stood up to him and said: "O Abu al-Yaqzan, you have made it light." He said: "Did you see me diminish any of its limits?" I said: "No." He said: "I hastened in it due to the forgetfulness of Satan. I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: 'Indeed, the servant performs the prayer, and nothing is written for him of it except a tenth of it, a ninth of it, an eighth of it, a seventh of it, a sixth of it, a fifth of it, a fourth of it, a third of it, or half of it.'"
حدثنا صفوان بن عيسى، أخبرنا ابن عجلان، عن سعيد المقبري، عن عمر بن الحكم، عن عبد الله بن عنمة قال: رأيت عمار بن ياسر دخل المسجد فصلى، فأخف الصلاة، قال: فلما خرج قمت إليه، فقلت: يا أبا اليقظان لقد خففت قال: فهل رأيتني انتقصت من حدودها شيئا؟ قلت: لا، قال: فإني بادرت بها سهوة الشيطان. سمعت رسول الله صلى الله عليه وسلم يقول: " إن العبد ليصلي الصلاة ما يكتب له منها إلا عشرها، تسعها، ثمنها، سبعها، سدسها، خمسها، ربعها، ثلثها نصفها "
