Hadith 4:189
Abu Usama narrated to us, Zakariya narrated to us, from Abu Ishaq, who said: I went on a military expedition with Ziyad ibn al-Nadr to the land of the Byzantines. He said: Ramadan began for us, and the people fasted, and among them were the companions of Abdullah: Amir ibn Sa’d, Sami’, Abu Abdullah, Abu Ma’mar, and Abu Musafi’. The people broke their fast one day while the sky was overcast, and we were between two mountains, al-Harith and al-Huwayrith. I did not break my fast until the night became clear. Then the sun came out, and we saw it upon the mountain. Ziyad said: "As for this day, we will make it up, for we did not intend to break our fast."
حدثنا أبو أسامة حدثنا زكريا عن أبي إسحاق قال غزوت مع زياد بن النضر ارض الروم قال فأهللنا رمضان فصام الناس وفيهم اصحاب عبد الله عامر بن سعد وسميع وابو عبد الله وابو معمر وابو مسافع فافطر الناس يوما والسماء ( ( ( والسماؤ ) ) ) مغيمة ونحن بين جبلين الحارث والحويرث ولم أفطر أنا حتى تبين الليل ثم ان الشمس خرجت فأبصرناها على الجبل فقال زياد اما هذا اليوم فسوف نقضيه ولم نتعمد فطره
