Tafsir of Al-Balad 90:2

And you are free in this city. he (Ibn Abbas) said, "O Muhammad! It is permissible for you to fight in it.'' Similar was reported from Sa`id bin Jubayr, Abu Salih, `Atiyah, Ad-Dahhak, Qatadah, As-Suddi and Ibn Zayd. Al-Hasan Al-Basri said, "Allah made it lawful (to fight in) for him (the Prophet ) for one hour of a day.'' The meaning of what they have said was mentioned in a Hadith that is agreed- upon as being authentic. In it the Prophet said,

إن هذا البلد حرمه الله يوم خلق السموات واﻻرض فهو حرام بحرمة الله إلى يوم القيامة

ﻻ يعضد شجره وﻻ يختلى خﻼه

وإنما أحلت لي ساعة من نهار

وقد عادت حرمتها اليوم كحرمتها باﻻمس أﻻ فليبلغ الشاهد الغايب

Verily, Allah made this city sacred on the Day that He created the heavens and the earth. Therefore, it is sacred by the sanctity of Allah until the Day of Judgement. Its trees should not be uprooted, and its bushes and grasses should not be removed. And it was only made lawful for me (to fight in) for one hour of a day. Today its sanctity has been restored just as it was sacred yesterday. So, let the one who is present inform those who are absent. In another wording of this Hadith, he said,

فٳن أحد ترخص بقتال رسول الله فقولوا إن الله أذن لرسوله ولم يٲذن لكم

So, if anyone tries to use the fighting of the Messenger (to conquer Makkah) as an excuse (to fight there), then tell him that Allah permitted it for His Messenger and He has not permitted it for you. Concerning Allah's statement,

ووالد وما ولد
