56) Ali bin Abi Talib (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "There is no Muslim who visits a (sick) Muslim early in the morning but seventy thousand angels send blessings upon him until evening comes, and if he visits him in the evening, seventy thousands angels send blessings upon him until morning comes, and he will have a garden in Paradise." Classed as saheeh by al-Albaani in Saheeh al-Tirmidhi.
57) A sin that is committed in secret is lighter in sanctity than one committed openly. Via Abu Hurairah the Prophet (peace be upon him) said that all of my Ummah is pardoned except for the mujahiroon (those who do things openly). Among [those] are people who do a deed during the night which Allah has hidden (from the eyes of others), then they go during the day and tell others that yesterday they did so and so. Whereas their Lord had concealed their wrongs overnight, they awake disclosing what their Lord had hidden. Bukhari and Muslim.
58) Participating in the holidays of the nonbelievers and congratulating them on them is part of imitating them and taking allegiance to them. Ibn ul-Qayyim said: it is haram by unanimous agreement; and if it is not considered kufr (disbelief) then it is at the very least forbidden and considered the same as one who congratulates one for prostrating to the cross.
59) Allah created the angels from light. The Prophet (peace be upon him) said: "The angels were created from light, the jinn were created from smokeless fire, and Adam was created from that which has been described to you." (From Muslim) The angels are by nature obedient to Allah: "[they i.e., angels] disobey not, [from executing] the Commands they recieve from Allah, but do that which they are commanded" [al-Tahreem 66:6- interpr. of meaning]
60) Angels are created in such a way that they do not eat or drink. Their food is glorification of Allah (tasbeeh) and saying Laa ilaaha ill-Allah (tahleel), as Allah tells us concerning them (interpr. of meaning): "They [i.e the angels] glorify His Praises night and day, [and] they never slacken [to do so]" [al-Anbiyaa' 21:20]
