Abu Waail reported,

Abdullah bin Masud said, "A man came to me today and asked me about a matter to which I did not know how to respond. He said, 'What do you say about a capable and energetic man who goes out with our commanders on military expeditions, and they impose upon us obligations we cannot even count?'I said to him, 'By Allah, I do not know what to tell you, except that we were with the Prophet ﷺ, and he would hardly impose anything upon us more than once before we carried it out. One of you will continue to be in a state of goodness as long as he fears Allah. When something troubles him in his heart, he asks a knowledgeable man who relieves him of it, but soon you will find no such man. By the One besides whom there is no god, I do not consider what remains of this world to be anything but the last gulps of a drink whose pure portion has been consumed and only its dregs remain.'"

عن أبي وائل قال

قال عبد الله بن مسعود: لقد أتاني اليوم رجل، فسألني عن أمر ما دريت ما أرد عليه، فقال: أرأيت رجلا مؤديا نشيطا يخرج مع أمرائنا في المغازي، فيعزم علينا في أشياء لا نحصيها؟ فقلت له: والله ما أدري ما أقول لك، إلا أنا كنا مع النبي ﷺ فعسى أن لا يعزم علينا في أمر إلا مرة حتى نفعله، وإن أحدكم لن يزال بخير ما اتقى الله، وإذا شك في نفسه شيء سأل رجلا فشفاه منه، وأوشك أن لا تجدوه، والذي لا إله إلا هو، ما أذكر ما غبر من الدنيا إلا كالنغب، شرب صفوه، وبقي كدره.
