Is it permissible to recite Surat Al-Baqarah every two or three days, if one is unable to recite it daily?

There is no specific time for reciting Surat Al-Baqarah. It is permissible to recite it daily, every two days, or weekly. Persevering in its recitation is recommended and rewarded.

Its virtues have been mentioned as follows: - It will come as an intercessor for its reciter on the Day of Resurrection, along with Surat Al-Imran. - Taking it is a blessing, and abandoning it is regret. Sorcerers cannot overcome it. - Whoever recites it in his house at night, the rebellious devils will not enter it for three nights. And whoever recites it during the day, the rebellious devils will not enter it for three days. - The last two verses of it are sufficient for its reciter at night from Qiyam al-Layl, from Satan, and from calamities.

Reciting the Quran frequently, in general, contains much good. And it will be said to the companion of the Quran on the Day of Resurrection: "Recite and ascend, and recite distinctly as you used to recite distinctly in the worldly life; for your station is at the last verse you recite."
