The Excellence of Observing Saum (Fasts) during Ramadan

Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "He who spends a pair in the way of Allah will be called from the gates of Jannah: 'O slave of Allah! This gate is better for you' and one who is constant in Salat (prayer), will be called from the Gate of Salat; and whoever is eager in fighting in the Cause of Allah, will be called from the Gate of Jihad; and who is regular in observing Saum will be called from Ar-Raiyan Gate. The one who is generous in charity will be called from the Gate of Charity." Abu Bakr (May Allah be pleased with him) said: "O Messenger of Allah ﷺ! May my mother and father be sacrificed for you! Those who are called from these gates will stand in need of nothing. Will anybody be called from all of those gates?" He replied, "Yes, and I hope that you will be one of them."

[Al-Bukhari and Muslim].

وعنه أن رسول الله ﷺ قال:" من أنفق زوجين في سبيل الله نودي من أبواب الجنة :يا عبد الله هذا خير، فمن كان من أهل الصلاة دعي من باب الصلاة، ومن كان من أهل الجهاد دعي من باب الجهاد، ومن كان من أهل الصيام دعي من باب الريان، ومن كان من أهل الصدقة دعي من باب الصدقة " قال أبو بكر، رضي الله عنه :بأبي أنت وأمي يا رسول الله ما على من دعي من تلك الأبواب من ضرورة، فهل يدعى أحد من تلك الأبواب كلها؟ قال: " نعم وأرجو أن تكون منهم ((متفق عليه))

Sahl bin Sa'd (May Allah be pleased with him):
The Prophet ﷺ said, "In Jannah there is a gate which is called Ar-Raiyan through which only those who observe Saum (fasting) will enter on the Day of Resurrection. None else will enter through it. It will be called out, "Where are those who observe fasting?" So they will stand up and proceed towards it. When the last of them will have entered, the gate will be closed and then no one will enter through that gate."

[Muslim].

وعن سهل بن سعد رضي الله عنه عنه عن النبي ﷺ قال: "إن في الجنة بابًا يقال له: الريان، يدخل منه الصائمون يوم القيامة لا يدخل منه أحد غيرهم يقال: أين الصائمون؟ فيقومون لا يدخل منه أحد غيرهم، فإذا دخلوا أغلق فلم يدخل منه أحد" ((متفق عليه))

Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "Every slave of Allah who observes Saum (fasting) for one day for the sake of Allah, Allah will draw his face farther from Hell-fire to the extent of a distance to be covered in seventy years."

[Al-Bukhari and Muslim].

وعن أبي سعيد الخدري، رضي الله عنه قال: قال رسول الله ﷺ " ما من عبد يصوم يومًا في سبيل الله إلا باعد الله بذلك اليوم وجهه عن النار سبعين خريفًا" ((متفق عليه))

Abu Hurairah (May Allah be pleased with him) reported:
The Prophet ﷺ said, "He who observes fasting during the month of Ramadan with Faith while seeking its reward from Allah, will have his past sins forgiven."

[Al-Bukhari and Muslim].

وعن أبي هريرة رضي الله عنه عن النبي ﷺ قال: من صام رمضان إيمانًا واحتسابًا، غفر له ما تقدم من ذنبه " ((متفق عليه))

Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "When Ramadan begins, the gates of Jannah are opened, the gates of Hell are closed, and the devils are chained."

[Al-Bukhari and Muslim].

وعنه رضي الله عنه أن رسول الله ﷺ قال: "إذا جاء رمضان فتحت أبواب الجنة، وغلقت أبواب النار، وصفدت الشياطين" ((متفق عليه))

Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "Observe Saum (fast) on sighting the crescent and terminate it on sighting it (the new moon), but if the sky is cloudy before you, then complete the number (thirty days) of the month."

[Al-Bukhari and Muslim].

وعنه أن رسول الله ﷺ قال: "صوموا لرؤيته، وأفطروا لرؤيته، فإن غَبِيَ عليكم فأكملوا عدة شعبان ثلاثين" ((متفق عليه وهذا لفظ البخاري)). وفي رواية مسلم: "فإن غم عليكم فصوموا ثلاثين يومًا".
