Second Year of Hijrah

Fasting

in the seocnd year of hijrah the fasting in the month of ramadan was made compulsory upon all adult muslims
quran says: “O you who believe, fasting is prescribed to you as it was prescribed to those before you, so that you may learn self-restraint.

in the second year of hijrah zakat was also made obligatory upon all rich muslim
quran says : and spend of your substance in the cause of Allah…..do good : for Allah loves those who do good.

by this time muslims used to pray facing the masjid e aqsa, qiblah e awal. for over 16months
in 2AH while prophet was leading asr prayer, it was revealed to him to switch to pray facing in the direction of kabah.
the whole congregation immediately turned its face.
quran says: we see the turning of your face to the heavens; now we shall turn you to a qiblah that shall please you. turn then your face in the direction of sacred masjid.

in 2AH Allah given the permission : ‘Fight in the cause of Allah those who fight you”
initially, as soon as prophet had reached madinah, quraish sent a message to madinans to hand over Holy prophet and muhajirs back to quraish,
Aus and khzrj refused to do so, as they themselves had invited the muslims.
Abu sufyan, one of the quraishi leaders was coming back from syria with his trade caravan. he feared while crossing from madinah nearby, that he might be attacked,
hence he called for army from makkah for protection,
another leader of quraish Abu jahl left with 1000 men army with 200 horses and 700 camels, while abu sufyan safely reached home, he called Abu jahl back.
Abu jahl refused to come back without a fight with muslims.
when prophet learnt about this he called muslims to take necessary steps, muhajir and ansar got together to protect. they managed to collect 313 men and 2 horses and 70 camels.
