Islamic historical events in Ramadhan

Today, Ustaz Zamri (of "Ustaz Zamri Bercerita" & "Mari Mengaji") was the invited speaker for the office's Ihya Ramadhan program. It was my first time attending a ceramah by him, and I stayed awake throughout the program (which is a huge compliment for the speaker with my history of sleeping during lectures/class).

Just want to share about historical events in Muslim calendar that happened in Ramadhan (perhaps as motivation of sort to work hard and not being "lembik longlai" during this blessed month...)

- Battle of Badar took place on 17 Ramadhan, Year 02 Hijri, in which 313 Muslims, of whom only 60 were armored, faced 1000 well-armed and equipped Musyrikin.
- The Opening of Makkah happened in Ramadhan, Year 08 Hijri
- Battle of Al-Qadisiyyah was won in Ramadhan, Year 15 Hijri. The battle is regarded as the decisive battle in the Islamic conquest of Persia, and a key to the conquest of Iraq.
- Opening of Andalus under Commander Tariq bin Ziyad happened in Ramadhan, Year 92 Hijri
- Construction of Al-Azhar Mosque, which later became the Al-Azhar University in Cairo, Egypt commenced in Ramadhan, Year 361 Hijri
- Salahuddin Al-Ayubi led the Muslims in evicting European Crusaders from Syria in Ramadhan 584H
- The Battle of Ain Jalut was won by the Egyptian Mamluks against the Mongols (Tartar) in Year 658 Hijri. The battle is considered by many historians to be of great macro-historical importance, as it marked the highwater point of Mongol conquests, and the first time they had ever been decisively defeated. After previous defeats, the Mongols had always returned and avenged the loss, but after the Battle of Ain Jalut they were unable to do so. The Mongol Ilkhanate leader Hulagu Khan was not able to advance into Egypt, and the Khanate he established in Persia was only able to defeat the Mamluks once in subsequent expeditions, briefly reoccupying Syria and parts of Palestine for a few months in 1300.
