Hawzah News Agency – The merciful prophet of Islam, peace be upon him and his household says:

لِلمُنافِقينَ عَلاماتٌ يُعرَفونَ بِها: تَحِيَّتُهُم لَعنَةٌ، وطَعامُهُم نُهمَةٌ، وغَنيمَتُهُم غُلولٌ، لا يَقرَبونَ المَساجِدَ إلّا هُجراً، ولا يَأتونَ الصَّلاةَ إلّا دُبُراً، مُستَكبِرينَ لا يَألَفونَ ولا يُؤلَفونَ، خُشُبٌ باللَّيلِ سُخُبٌ بالنَّهارِ.

'Hypocrites have signs through which they are known: their greeting is cursing, their food is greed [gluttony], their earnings are through breaches of trust, they do not come close to the mosques save with contempt, they fulfil their prayers at the very last moment, [they are] haughty people who do not socialize and are not sociable, they are as wood in the night, loud in the day.'
