Establishing Circles of Remembrance
① It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said:
إذا مررتم برياض الجنة فارتعوا
"When you pass through the gardens of Paradise, eat and drink to your fill."
The noble companions (may Allah be pleased with them) asked:
"O Messenger of Allah! What is meant by the gardens of Paradise?"
The Noble Prophet (peace be upon him) said:
حلق الذكر
"Circles of remembrance."

ينزل ربنا كل ليلة إلى سماء الدنيا حين يبقى ثلث الليل الآخر فيقول : من يدعوني فأستجيب له ، من يسألني فأعطيه ، من يستغفرني فأغفر له
"Our Lord descends every night when one-third of the night remains to the lowest heaven and says: Who is there to call upon Me so that I may answer him? Who is there to ask Me so that I may give him? Who is there to seek My forgiveness so that I may forgive him?"

ما من عبد مسلم يدعو لأخيه بظهر الغيب إلا قال الملك : ولك بمثل
