Volume 3, Book 34, Number 263:
Narrated Abu Huraira (radiallaahu `anhu):
You people say that Abu Huraira (radiallaahu `anhu) tells many narrations from Allah’s Apostle (sallallaahu `alayhi wasallam) and you also wonder why the emigrants and Ansar do not narrate from Allah’s Apostle (sallallaahu `alayhi wasallam) as Abu Huraira (radiallaahu `anhu) does. My emigrant brothers were busy in the market while I used to stick to Allah’s Apostle (sallallaahu `alayhi wasallam) content with what fills my stomach; so I used to be present when they were absent and I used to remember when they used to forget, and my Ansari brothers used to be busy with their properties and I was one of the poor men of Suffa. I used to remember the narrations when they used to forget. No doubt, Allah’s Apostle (sallallaahu `alayhi wasallam) once said, “Whoever spreads his garment till I have finished my present speech and then gathers it to himself, will remember whatever I will say.” So, I spread my colored garment which I was wearing till Allah’s Apostle (sallallaahu `alayhi wasallam) had finished his saying, and then I gathered it to my chest. So, I did not forget any of that narrations.
Imam Bukhari mentions this Hadith in the beginning of Book of Sales and Trade under the chapter:
فَإِذَا قُضِيَتِ الصَّلَوةُ فَانتَشِرُواْ فِى الاٌّرْضِ وَابْتَغُواْ مِن فَضْلِ اللَّهِ وَاذْكُرُواْ اللَّهَ كَثِيراً لَّعَلَّكُمْ تُفْلِحُونَ
Then when the Salah is complete, you may disperse through the land, and seek the bounty of Allah, and remember Allah much, that you may be successful. [Al-Jumu`ah: 10]
Ibn Kathir says in his tafsir about this ayah:
﴿فَإِذَا قُضِيَتِ الصَّلَوةُ﴾
(Then when the Salah is complete,) means, when the Friday prayer is finished,
﴿فَانتَشِرُواْ فِى الاٌّرْضِ وَابْتَغُواْ مِن فَضْلِ اللَّهِ﴾
(you may disperse through the land, and seek the bounty of Allah,) After Allah forbade Muslims from working after hearing the Adhan and ordered them to gather for the Friday prayer, He allowed them to spread throughout the earth and seek bounty after the prayer is finished. Ibn Abi Hatim recorded that when the Friday prayer finished, `Irak bin Malik would stand by the gate of the Masjid and invoke Allah, saying, “O Allah! I have accepted and complied with Your Call, performed the prayer You ordered and dispersed as You ordered me. Therefore, grant me of Your favor and You are the best of those who grant provisions.” Allah’s statement,
﴿وَاذْكُرُواْ اللَّهَ كَثِيراً لَّعَلَّكُمْ تُفْلِحُونَ﴾
(and remember Allah much, that you may be successful.) means, while you are buying and selling, giving and taking, remember Allah much and do not let this life busy you from what benefits you in the Hereafter. There is a Hadith that states,
«مَنْ دَخَلَ سُوقًا مِنَ الْأَسْوَاقِ فَقَالَ: لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، كَتَبَ اللهُ لَهُ أَلْفَ أَلْفِ حَسَنَةٍ وَمَحَا عَنْهُ أَلْفَ أَلْفِ سَيِّئَةٍ»
(Whoever enters a marketplace and says, “La ilaha illallah, He is alone without partners, His is the sovereignty and His is the praise, and He is Able to do all things.” Then Allah will record a thousand-thousand (a million) good deeds for him and will erase a thousand-thousand evil deeds.) Mujahid said, “A servant (of Allah) will not be among those who remember Allah often, until he does so while standing, sitting and lying down.”
