عن زيد بن ثابت رضي الله عنه قال سمعت رسول الله صلى الله عليه وسلم يقول نضر الله امرأ سمع منا حديثا فحفظه حتى يبلغه فرب حامل فقه إلى من هو أفقه منه ورب حامل فقه ليس بفقيه (سنن أبي داود #3662)

Hazrat Zaid bin Thaabit (radhiyallahu ‘anhu) reports, “I heard Rasulullah (sallallahu ‘alaihi wasallam) saying, ‘May Allah Ta‘ala bless that person with beauty who hears a Hadith from us, and thereafter memorizes it until he conveys it (to others). There are many who carry the knowledge of Fiqh (i.e. they are in possession of Ahaadith which relate to laws of Shari‘ah) and convey it to those who are more understanding than them, and there are many who carry the knowledge of Fiqh yet do not possess the understanding of it.”

عن عبد الله بن مسعود قال قال النبي صلى الله عليه وسلم لا حسد إلا في اثنتين رجل آتاه الله مالا فسلط على هلكته في الحق ورجل آتاه الله الحكمة فهو يقضي بها ويعلمها (صحيح بخاري #73، صحيح مسلم #816)

Hazrat ‘Abdullah bin Mas‘ood (radhiyallahu ‘anhu) narrates that Rasulullah (sallallahu ‘alaihi wasallam) said, “Envy is not permissible except in regard to two types of people. The first person is the one whom Allah Ta‘ala has blessed with wealth and Allah Ta‘ala blesses him with the ability to spend it in the correct manner. The second person is the one whom Allah Ta‘ala has blessed with Deeni knowledge, and he correctly practices upon it and imparts it to others.”

عن عائشة رضي الله عنها أن رسول الله صلى الله عليه وسلم كان إذا اشتكى نفث على نفسه بالمعوذات ومسح عنه بيده فلما اشتكى وجعه الذي توفي فيه طفقت أنفث على نفسه بالمعوذات التي كان ينفث وأمسح بيد النبي صلى الله عليه وسلم عنه وفي رواية أخرى لها قالت وأمسح بيد نفسه لبركتها ( صحيح بخاري #4439،5735 )

It is reported from Hazrat ‘Aa’ishah (radhiyallahu ‘anha) that whenever Rasulullah (sallallahu ‘alaihi wasallam) would fall ill, he would recite the Mu‘awwizaat (words of seeking protection i.e. Surah Falaq and Surah Naas and in some narrations, Surah Ikhlaas) and blow upon himself (i.e. he would blow into his hands) and pass his hands over his blessed body. When he (sallallahu ‘alaihi wasallam) fell into his final illnesss (and was unable to recite and pass his blessed hands over his body), I began to recite the Mu‘awwizaat which he would recite and blow on his body, and I would blow into the blessed hand of Rasulullah (sallallahu ‘alaihi wasallam) and pass it over his body.” In another narration, Hazrat ‘Aa’ishah (radhiyallahu ‘anha) mentioned, “I would blow into the blessed hand of Rasulullah (sallallahu ‘alaihi wasallam) and thereafter pass it over his body on account of his hand having the blessing (i.e. I would not blow into my own hands as my hands do not possess the blessing that is in the hand of Rasulullah (sallallahu ‘alaihi wasallam)).”

عن أبي هريرة عن النبي صلى الله عليه وسلم قال إياكم والظن فإن الظن أكذب الحديث ولا تحسسوا ولا تجسسوا ولا تحاسدوا ولا تدابروا ولا تباغضوا وكونوا عباد الله إخوانا (صحيح بخاري #6064)

Hazrat Abu Hurairah (radhiyallahu ‘anhu) narrates that Rasulullah (sallallahu ‘alaihi wasallam) said, “Refrain from suspicions (and ill thoughts regarding people), for indeed suspicions are the most false of all inner thoughts. Do not search for the faults of people, do not spy on them, do not bear jealousy for one another, do not turn your backs and forsake one another, and do not harbor enmity for one another. And live as brothers, O servants of Allah!”
