Withdraw to the masjid for worship in the last ten nights of Ramaḍān. ʿĀʾishah said: “The Prophet ﷺ would observe iʿtikāf in the last ten days of Ramaḍān until Allah took him, then his wives observed it after him.” (al-Bukhārī & Muslim).
العربية: عن عائشة رضي الله عنها أنّ النبيّ ﷺ «كان يعتكف العشر الأواخر من رمضان حتى توفّاه الله، ثم اعتكف أزواجه من بعده». (البخاري ومسلم).
Even a partial iʿtikāf — a night or a day in the masjid — revives this Sunnah; do what you can.
