Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Those who love one another for the sake of Allah will be in the shade of Allah's Throne, on the day when there is no shade except His shade. People will be terrified but they will not be terrified, and people will be afraid but they will not be afraid." Abu Idris al-Khawlani (may Allah have mercy on him) said: Then I got up from him (Sayyiduna Mu'adh (may Allah be pleased with him)) and came to Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him), and he said: And (what is) better than that (is that) I heard the Messenger of Allah (peace and blessings be upon him) say: "My love is due to those who love one another for My sake, My love is due to those who sit together for My sake, and My love is due to those who visit one another for My sake."
